Synthetic Route of 1552-42-7, Chemistry is the experimental science by definition. We want to make observations to prove hypothesis. For this purpose, we perform experiments in the lab. 1552-42-7, Name is Crystal violet lactone,introducing its new discovery.
Simultaneous photoinduced color formation and photoinitiated polymerization
Crystal violet lactone (CVL, 1) is one of a series of important commercial materials that form the basis of the ‘carbonless’ carbon paper response by turning from ‘colorless’ to ‘colored’ in the presence of acid. Crystal violet lactone (CVL, 1, 3, 3-bis[4-(dimethylamino)phenyl]-6-(dimethylamino)-1(3H)- isobenzofuranone) and other lactone dye precursors 2-5 form colored triphenylmethyl cations when irradiated with UV light in the presence or absence of [4-(octyloxy)phenyl]phenyliodonium hexafluoroantimonate (OPPI). In selected monomers in the presence of iodonium salt, color formation and polymerization occur simultaneously. The excited singlet state lifetimes of 1-5 estimated from quantum yields for the disappearance of CVL in the presence of OPPI are similar to those observed for fluorescence quenching and occur mainly by electron transfer. On the basis of the transient absorption spectra, it can be concluded that triarylmethane cations are generated from the lactone precursors in the presence of OPPI in acetonitrile with a pseudo first order rate constant of 104 s-1. Color formation in the absence of OPPI is suggested to occur from the excited singlet states of the lactone via a biradical formed by photoinduced beta-bond cleavage.
We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 1552-42-7, and how the biochemistry of the body works.Synthetic Route of 1552-42-7
