Paper Abstract

Our research was aimed at finding a photochromic compounds sensitive in the visible spectra. We have reported a new photochromic composite polymer materials consisting of carbazole-contained polymers, which are doped by spiropyran dyes. We have synthesized and experimentally characterized such photochromic polymers. The experimental measurements of its absorption characteristics are evaluated in conjunction with its potential applications for optical holography. Both recording and erasing procedures are possible using direct radiation from a blue line of an Ar laser (X=458nm). Also, simple diffraction gratings have been recorded by the use of two-color recording procedure ensuring artificial negativity in the visible spectra. Two structures of high-sensitive carbazole-contained photochromic compounds are proposed. Keywords: Holography, polymers, photochromic compounds, absorption spectra, diffraction efficiency
