For the purpose of extending the color-change range of thermochromic materials, the new thermochromic microcapsules (TCMs) were designed by combining thermochromic materials with optimized dispersive-cationic dyes. Three types of TCMs, which displayed three primary colors of red, yellow and blue when exposed to high temperature, were prepared separately. By color matching with three-primary colors, the matched TCMs could present remarkable thermochromic properties. Especially, with the variety of ambient temperature, the colors of the TCMs could change reversibly between different tones and exhibit more gorgeous colors than common thermochromic materials, which made it possible to solve the problem of the narrow color-change range for common thermochromic material. In this paper, the mechanism of expanding thermochromic colors, thermochromic performances, color matching effects and thermal stabilities of the TCMs and the modified fabrics were investigated. The TCMs were of practical significances for developing thermochromic intelligent textiles.

The development and implementation of processes to store and/or transport thermal energy can be very useful to regulate the temperature of a system and to make a better use of renewable and non-renewable energy resources. It has been shown that some microencapsulated phase change materials (MPCMs) and nanoencapsulated phase change materials (NPCMs) can be used to store and/or transport thermal energy efficiently as latent heat. The composition of these materials has an effect on several properties, like their thermal conductivity, that can affect their performance. Some strategies to modify the composition of these materials developed in the last decade can be useful to improve the characteristics of these materials. A more complex composition can also enable these materials to carry out other functions, besides storing thermal energy, that can improve their performance and extend the range of possible applications of these materials. This work gathers some of these recent developments to emphasize how some of these strategies can be useful to improve the characteristics of these materials and the potential of multifunctional MPCMs and NPCMs in several applications like solar photo-thermal conversion and catalysis.

The green BCG/MgCl2/PEG-g-CDA powders were synthesized at different temperatures via liquid-phase reaction method. The microstructures of the synthesized powders were analyzed and characterized by FT-IR, XRD and ChemDraw software. The effects of synthesized temperatures on infrared emissivity properties of the powders in the wavelength range 3?5 mum were investigated systematically. It is found that the powders heated at 100 C exhibit the optimum crystallinity at room temperature and thus show the largest variation (0.4) in infrared emissivity with the test temperature varying from 50 C to 65 C. Furthermore, the mechanisms for the self-regulated infrared emissivity properties are also explored thoroughly. The variation of infrared emissivity with temperature is ascribed to the changes in resistivity, which is induced by the transformation of PEG-g-CDA between crystalline and amorphous as well as the molecular structure transition of BCG between quinone and lactone. Our results suggest that BCG/MgCl2/PEG-g-CDA powders are potential candidates for intelligent infrared camouflage.

This review presents the state-of-the-art of optical sensors for determination of biogenic amines (BAs) in food by publications covering about the last 10 years. Interest in the development of rapid and preferably on-site methods for quantification of BAs is based on their important role in implementation and regulation of various physiological processes. At the same time, BAs can develop in different kinds of food by fermentation processes or microbial activity or arise due to contamination, which induces toxicological risks and food poisoning and causes serious health issues. Therefore, various optical chemosensor systems have been devised that are easy to assemble and fast responding and low-cost analytical tools. If amenable to on-site analysis, they are an attractive alternative to existing instrumental analytical methods used for BA determination in food. Hence, also portable sensor systems or dipstick sensors are described based on various probes that typically enable signal readouts such as photometry, reflectometry, luminescence, surface-enhanced Raman spectroscopy, or ellipsometry. The quantification of BAs in real food samples and the design of the sensors are highlighted and the analytical figures of merit are compared. Future instrumental trends for BA sensing point to the use of cell phone?based fully automated optical evaluation and devices that could even comprise microfluidic micro total analysis systems.

Nowadays, urged by the high demand to reduce paper consumption, rewritable paper receives more and more attention. However, it is a great challenge to conveniently fabricate the rewritable paper which has long legible time of information and is easy to use simultaneously. Here, we report a new type of long-lasting rewritable paper based on color-memorizing thermochromic dye and photothermal-converting toner, which is fabricated by a two-step printing process. The rewritable paper demonstrates excellent rewriting performances (legible time > 6 months and reversibility > 100 times). The thermochromic effect is based on a temperature-driven phase change mechanism, accompanied by a lactone ring tautomerism of crystal violet lactone. The color of the rewritable paper rapidly changes from blue to colorlessness when the temperature is higher than 65 C, and the colorless state can be maintained at room temperature. The color returns to blue when the temperature is lower than -10 C. By using an electrothermal pen, a thermal printer, and near infrared (NIR) light, characters and images with high resolution can be handwritten, thermal-printed, and photoprinted on the rewritable paper. The written/printed information can be cleaned under lower temperature or can be quickly erased by NIR light. This rewritable paper is easy for large-scale production and will have promising opportunities in practical applications, such as long-lasting information recording and reading, rewritable label, reprintable displays, and so on.

Thermochromic microcapsules with two kinds of phase change materials that can change color with gradient under 70 C were prepared. To induce gradient color change in the thermochromic microcapsules, two phase change materials containing polyurea microcapsules in the core were prepared by simply mixing two different melting points and dye. The color change displayed a gradient from dark to light blue due to the difference in melting point in the two phase transition materials. The microcapsules prepared in this study were made from a display that showed characters by coloring and decoloring two colors by inculcating a substance that is melts at 21 C and 53 C. In addition, the thermochromic microcapsules designed in this study showed potential future application for color convertible smart windows.

1552-42-7, Name is Crystal violet lactone, belongs to benzofurans compound, is a common compound. Application In Synthesis of Crystal violet lactoneIn an article, once mentioned the new application about 1552-42-7.

Leuco dye?developer?solvent composites with thermochromic properties were studied. The applied 1-dodecanol solvent shows beta crystalline, alpha solid (rotator) and liquid phases. The inclusion of the crystal violet lactone dye increases transition temperatures of all phases and strengthens the alpha phase. The benzyl 4-hydroxybenzoate developer causes opposite effects and prevents the appearance of the alpha phase. These consequences combine in ternary composites, where lower transition temperatures were obtained as in the solvent, but the alpha phase is formed more likely as expected due to the presence of the developer. The hydration of the composite strengthens its crystalline network, but makes alpha phase more unstable. The thermal properties were related to the temperature-dependent colour. Composites with well-resolved alpha and beta phases at cooling show a typical colour hysteresis. If only weak alpha phase or none at all was found in DSC curves, the colour hysteresis has an unusual shape with heating and cooling curves crossing each other. The hydration of the composite changes the colorimetric properties in accordance with the relation found for anhydrous composite. More conclusions and interrelations between the two properties require application of other analytical methods.

In this study, a series of reversible thermochromic microencapsulated phase change materials (TC-MPCMs), exhibiting excellent thermal energy storage performance, were designed and fabricated successfully. The core of TC-MPCMs was comprised of crystal violet lactone employed as thermochromic colorant, bisphenol A as developer and 1-tetradecanol as co-solvent, respectively. The effects of shell materials on reversible thermochromic properties, thermal performance and thermal stability of TC-MPCMs were investigated systematically as well. These influencing factors of encapsulation process such as the dripping speeds, SMA emulsifier and pH were carried out to optimize the encapsulation parameters. Additionally, the TC-MPCMs modified with fabricated silver nano-particles displayed excellent thermal properties, heat transfer and antibacterial activity. Both the microscopic morphology and microstructure of TC-MPCMs were characterized and discussed systematically. The thermal distribution on the TC-MPCMs was exhibited via the infrared camera. The performance of fusion, crystallization, enthalpy and thermal stability of various capsules were measured and studied as well. In the end, ultraviolet?visible spectrophotometry was employed to investigate the antibacterial activity of Ag-TC-MPCMs(B). Furthermore, the TC-MPCMs(B) and Ag-TC-MPCMs(B) exhibited excellent thermal stability and the cyclic durability.

Multiphoton absorption (MPA) is an enabling technology for many applications. However, due to the low probability of MPA processes, their accurate characterization remains a challenge. Here we introduce a new technique, two-beam constant emission intensity (2-BCEIn) spectroscopy, that offers substantial advantages over other existing methods that use the generation of optical emission for the characterization of absorptive nonlinearities. We use 2-BCEIn to study nonlinear absorption in solutions of crystal violet lactone (CVL) over a range of excitation wavelengths in which the dominant nonlinear absorption process transitions from two-photon absorption (750 nm) to three-photon absorption (830 nm). At an excitation wavelength of 800 nm, both two-photon absorption and three-photon absorption contribute substantially to the nonlinear fluorescence excitation (NFE) signal, although the dynamic range of the NFE data is not sufficient to quantify the contributions of each process. 2-BCEIn spectroscopy enables the direct measurement of the local exponent at each emission intensity. 2-BCEIn measurements made at several different emission intensities demonstrate unambiguously that the nonlinear excitation of CVL at 800 nm cannot be described solely as the sum of a two-photon process and a three-photon process. A kinetic model that includes intrapulse excited-state absorption reproduces the features of the 2-BCEIn measurements and enables the determination of the ratio of the three-photon absorption cross section to the two-photon absorption cross section. Such information cannot easily be extracted from conventional NFE measurements. These results demonstrate the power and versatility of two-beam action spectroscopies for elucidating the complex photophysics of multiphoton absorption processes.
