Syntheses and Characterisitics of New Photochromic Spiroxazine Dyes

새로운 광변색성 Spiroxazine색소의 합성과 특성

The Aggregation State of thin vapor deposite Film made by Cyanine Dye were changed into Monomeric molecular state(M) and Dimeric Aggregation(D) at the acidic treatment, into reversible H-Aggregation (H) at alkalic gas or heat treatment. Photo-electric properties were higher H than D and M, this stats were effective in enhancing Photoelectric-conversion characteristic. Substitute group of Meso-Position being stronger electronic Donors, Electronic density is higher and Electric conductivity is enhanced, we confirmed Oscillator Strength calculated by PPP-Molecular Orbital Calculation and Absorption Spectra at solvent stats were agreed good.
