Photolysis mechanism of a squarylium dye

The photodegradation mechanism of a squarylium dye was investigated by analyzing the photoproducts using a UV-Vis spectrometer, MALDI-TOF-MASS, HPLC and GC-MS. We found that a squarylium dye was likely decomposed into smaller species by way of an intermediate species which was an adduct of an original dye with a solvent molecule or solvent radical. The reaction mechanism was confirmed using the quantum chemical calculation by estimating the structure of the intermediate species. Since the solvent molecules are involved in the reaction, the reaction rate depended on the used solvent, and the photodegradation rate was much faster in a chloromethane than in an alcohol.

Synthesis, characterization and photochromic studies in film of heterocycle-containing spirooxazines

A series of novel heterocycle-containing spirooxazines have been designed and synthesized, and their photochromic properties were investigated under flash photolysis and continuous irradiation in particular regard to the fatigue resistance, the lifetime of the colored merocyanine form in various solutions and polymers. Especially, the characteristics of two UV-sensitive spirooxazines dispersed polymethylmethacrylate thin-films were extensively studied. Detailed studies showed that general significant shifts in the λmax of the absorption spectra of the open forms, interesting fatigue resistances and emission fluorescene properties were observed.

PHOTOCHROMISM. SYNTHESIS AND PROPERTIES OF INDOLINOSPIROBENZOTHIOPYRANS

Novel photochromic compounds, indolinospirobenzothiopyrans, were prepared and their properties in polymer films were examined.The absorption bands of the colored form lie around 100 nm deeper in the long-wave region of the spectrum than are the case with the common spiropyrans.

The Chlorination of Some N,N-Dimethylanilines with 1,3,5-Trichloro-1,3,5-triazine-2,4,6-(1H,3H,5H)-trione (Trichloroisocyanuric Acid)

The reaction of some representative N,N-dimethylanilines and of Fischer's base (1,3,3-trimethyl-2-methyleneindoline) with trichloroisocyanuric acid in concetrated sulfuric acid has been investigated.In many cases mixtures of chlorinated products were obtained; these mixtures were examined both by gas-liquid chromatography and by proton magnetic resonance spectroscopy.The reaction of N,N-dimethylaniline with dichloroisocyanuric acid was also studied.A feature of these chlorinations is the marked tendency for substitution to occur ortho to the dimethylamino group.This behaviour therefore differs from that reported for the corresponding brominations involving dibromoisocyanuric acid, where meta-substitution was observed.
