In this article, the photophysics of Crystal Violet Lactone (CVL) in aqueous and non-aqueous reverse micelles (RMs) have been explored using UV-vis absorption, steady-state emission and picosecond time-resolved fluorescence emission spectroscopic techniques. CVL exhibits dual emission bands (CTA and CTB states of CVL) in a polar aprotic solvent, whereas when this molecule is entrapped in the RMs, it exhibits a single emission band (CTA). In the case of all the RMs, the CTA ? CTB transformation is retarded due to the influence of polarity, viscosity and proticity. Moreover, in the case of viscous solvents (ethylene glycol and glycerol), a single emission band is found. The hydrogen-bond-donating solvent molecule also quenches the CTB emission band of CVL. This is the first report on the photophysics of the CVL molecule in biomimicking organised assemblies, in which the opposite spectral features were observed in the RMs at different excitation wavelengths. The average rotational relaxation time increases in the respective RMs compared to their respective solvent, with the exception of neat glycerol, wherein the rotation of CVL is practically hindered. In the case of EG and glycerol RMs, the rotational relaxation is even more retarded due to the gradual swelling of the RM cores. Herein, the hydrodynamic friction, coupled with the dielectric friction, causes such rotational motion to be quite slow.

1552-42-7, Name is Crystal violet lactone, belongs to benzofurans compound, is a common compound. COA of Formula: C26H29N3O2In an article, once mentioned the new application about 1552-42-7.

In an acetonitrile solution, the extents of ionization of trityl halides (Ph3CX: X = Cl, Br) in the presence of various concentrations of alkali metal (M+ =Li+, Na+) and alkaline-earth metal (M2+ = Mg2+, Ca2+, Sr2+, Ba2+) perchlorates were examined by spectrophotometry. The promoted formation of the trityl ion (Ph+C-) in the presence of metal ions was attributed to “chemical” interactions, such as coordination or covalent bonding between the halide ions and M- or M2+ ions, and not merely the electrostatic interaction. The salt effects increased with methoxy-substituents on trityl chloride as non-substituted < 4-methoxy < 4,4?-dimethoxy< <4,4?,4?-trimethoxytrityl. At higher RX (or X-) concentrations, not only "coordination", but also precipitation reactions between X and M+ or M2+ (except for Li- and Mg2+) seemed to promote the ionization of RX. In the co-presence of a small amount of CH3SO3H, trityl benzoate gave the Ph3C- ion upon the addition of LiClO4 or Mg(ClO4)2. A red color with strong fluorescence due to the zwitterion (R+COO-) of Rhodamine (Rhodamine B base) was observed upon the addition of M+ and M2+, which should have been caused by an interaction between the metal ions and the intramolecule carboxylate (from the gamma-lactone) of Rhodamine in the solution. The gamma-lactone ring of Crystal Violet lactone in acetonitrile was cleaved by the addition of Mg(ClO4)3 to give a strong violet color, whereas, LiClO4, NaClO4, or Ba(ClO4)2 had no (or very small) effects in the solution. It was found that the interactions between X- or RCOO- and M2+ or M- in cetonitrile were strong enough to promote the ionization of partly ionized ciovalent bonds. Do you like my blog?

One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, HPLC of Formula: C26H29N3O2, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 1552-42-7, Name is Crystal violet lactone, molecular formula is C26H29N3O2

A reversible, adjustable thermochromic colorant with bichromatic conversion from dark red (cool state) to yellow (heat state) was prepared using bromocresol purple (BCP) as colour former. The thermochromic behaviour of this colorant was investigated during the heating-cooling cycle, including the colour depth, colour difference and switching temperature. The mechanism of thermochromic colorant switching between dark red and yellow originated from the transformation of the conjugated structures of BCP, which was confirmed by infrared spectrometry. The switching temperature can be flexibility adjusted between 13?46 C by mixing solvents according to Schroeder’s equation, which was demonstrated by differential scanning calorimetry measurement. The thermochromic colorant presented good reversible thermochromic performance with stable changes in colour parameters for 50 heating-cooling cycles. This sultone-based reversible dark red-yellow conversion thermochromic colorant is suitable for application as thermal-indicating material under various conditions.

A method to differentiate between carbonless copy papers and to date the ink entries on those papers has been developed based on ultra-high-performance liquid chromatography and mass spectrometric methods. A total of 52 paper samples were distinguished and classified according to compositional differences reflected by their chromatograms, with a discrimination power as high as 99.3%. The degradation kinetics of a common dye, crystal violet lactone, was investigated, and a quantitative determination method for the dye and its decomposition products was established. The results showed that relative peak area for both the dye and its degradation products versus aging time exhibits satisfactory linearity, which was utilized to date the ink entries on the samples. Overall, this work details an approach that can discriminate between different samples on the basis of compositional differences and describes the degradation rate of the dye, which can be used to age and authenticate ink entries.

A ‘solvent facilitated’ coaxial electrospinning process was used to produce reversible narrow temperature gap thermochromic, core-shell fibres. A thermochromic composite composed of crystal violet lactone (the leuco dye), bisphenol A (the developer) and 1-dodecanol (the phase-change solvent) was entrained as core material inside poly(methyl methacrylate) shells. A mutual core and shell solvent (chloroform) was used to obtain low interfacial tension between the core and shell spinning solutions. This enabled room temperature entrainment of the low molecular weight, low viscosity core fluid. In order to minimize the effect of light scattering and subsequently produce fibres with visible colour transitions, the fibres were produced with external diameters of 3-8mum and core diameters of 1.7-5.7mum. In order to produce core-shell fibres with repeated, reversibly thermochromic behaviour and a stable colour developed state, it was necessary to entrain a dye composite that contained an excess developer, essentially making this composite non-thermochromic prior to entrainment. The fibres were analyzed using SEM and DSC.

The photosensitive color-producing microcapsules have been prepared with melamine/formalin resin by in situ polymerization method. The leucocompound and the photoacid generator dissolved in diisopropylnaphthalene were successfully loaded in the interior of microcapsules. Preparation of microcapsules that have uniform particle size could also be attained. Irreversible development of microcapsules was examined by an irradiation of UV light. The leucocompound in the microcapsule was sensitively reacted with the acid produced from the photoacid generator without destruction of capsule walls. It has also been found that the development in the microcapsule progresses quickly compared to the bulk condition.
