PREPARATION AND PHOTOCHROMIC BEHAVIOR OF ORMOSIL CONTAINING ENCAPSULATED AGTCNQ MOLECULES

Preparation and photochromic behavior of ormosil containing encapsulat ed AgTCNQ molecules were studied in this paper. The ormosil resulted f rom hydrolysis and polycondensation of glycidoxypropyltrimethoxysilane , dimethyldimethoxysilane and methyltrimethoxysilane. The time to add AgNO3 water solution into the resultant sol was a key factor to synthe size AgTCNQ molecules inside ormosil matrix. AgTCNQ molecules encapsul ated in the ormosil showed different photochromic behavior compared wi th pure AgTCNQ film: normal photochromic reaction can be realized, whi le reverse photochromic reaction can not. The ''cage'' model was used to explain this phenomenon.
