A study was conducted to demonstrate amplification of the coloration efficiency of photochromic oxazines. It was demonstrated that the coloration efficiency of the resulting biochromophoric photochromes can be significantly greater than that of their monochromophoric samples. Researchers designed a biochromophoric compound, based on the photoinduced opening and thermal closing of a (1,3)oxazine ring, on the basis of these considerations. The study also focused on illustrating the design logic and demonstrate the synthesis and photochemical properties of a representative sample of the novel class of biochromophoric photochromes. The synthesis reaction was monitored by thin-layer chromatography, using aluminum sheets coated with silica.
