Abstract

The effect of photo irradiation on the refractive index of spirobenzopyran (SP) polymer was investigated. Spirobenzopyran polymers were prepared by a radical polymerization using 6-(p-methacryloyloxy-hexyloxyphenyl)carbonylspirobenzopyran, styrene, and butylmethacrylate. Films with spirobenzopyran polymers showed color change from pale yellow to deep blue upon irradiation of a monochromatic light of 340 nm. The colored films were bleached either spontaneously or by light of 580 nm. The refractive index changes of the spirobenzopyran polymers were 5×10 -4 and 9×10 -4 for 20 wt% and 35 wt% of the spirobenzopyran content, respectively.
