Abstract
Abstract Comparative studies have been performed on the formation of surface relief grating (SRG) using an amorphous molecular material, 4-[di(biphenyl-4-yl)amino]azobenzene (DBAB), and a vinyl polymer containing DBAB as a pendant chromophore. It was found that SRG was formed more rapidly for the photochromic amorphous molecular material than for the corresponding vinyl polymer.
