    Abstract:
    Absorption spectra of photochromic spironaphthoxazine dye in various solvents were examined and exhibited a positive solvatochromism. The positive solvatochromism of this dye strongly suggests that the structure of open chain forms is keto type structure, 4a. The effect of structural change on the electronic spectra, on replacement of the C=C bond by C=N bond, is discussed.

    Abstract Photochromism of N-salicylideneanilines and related compounds was studied by measuring the electronic and vibrational spectra of the transient species. The rise time of the transient electronic spectra of the photochromic colored species was measured by picosecond time-resolved spectroscopy and was found to be dependent upon solvent viscosity. FT IR spectra showed that the photochromic colored species took the keto amine form. Picosecond kinetic analysis demonstrated that an intermediate existed in the transfer process from cis-keto amine to the photochromic species. These facts led us to the conclusion that the photochromic phenomenon of N-salicylideneanilines occurred through enol imine\oversethν→enol imine*→cis-keto amine*→the intermediate→trans-keto amine (photochromic species).

    Abstract Phenylazoacetoacetanilide and its related compounds have the hydrazone structure. The phenylazoacetoacetic acid ethylester, for example, forms an intramolecular hydrogen bond between a ketone group and a hydrazone group in the solid state and in non-polar solvents. The electronic absorption spectra exhibit three groups of bands—A,B and C—D. The effects upon the spectra of the intramolecular hydrogen bond and of the π-p conjugation at the carboxylic acid amide group have been discussed.

    Spectral-fluorescent properties of a series of merocyanine dyes comprising the barbituric acid residue as the electron-accepting terminal group are investigated in comparison with those of their N,N-methylated analogues in media of various polarity. It is revealed that in polar aprotic solvents the electronic absorption spectra of the studied compounds are influenced dramatically by the formation of hydrogen bonds between the NH-groups of barbituric residue and solvent molecules. An effect of such nucleophilic solvation on the electronic structure of the studied dyes is analysed using both the spectral data obtained and the DFT/B3LYP quantum chemical simulation. It is found also, that solvation has comparatively weak influence on the shape and position of the fluorescence bands of the studied merocyanines while the fluorescence quantum yield changes substantially in solvents of various polarity.
