Organic-inorganic hybrid gels containing fluorescent molecules, pyrene, anthracene, pelyrene, 9,10-diphenylanthracene, were synthesized from multi-functional cyclic siloxane, 1,3,5,7-tetramethylcyclotetrasiloxane (TMCTS), or cubic silsesquioxane, 1,3,5,7,9,11,13,15-octakis(dimethylsilyloxy)pentacyclo-[9,5,1,1,1,1]octasilsesquioxane (POSS), as crosslinking reagents with α,ω-nonconjugated dienes, 1,5-hexadiene (HD) or 1,9-decadiene (DD), as spacer monomers, using a photo hydrosilylation reaction with a bis(acetylacetonato)platinum catalyst in toluene. The gels containing pyrene showed higher emission intensity than the toluene solution of pyrene. The emission intensity of pyrene increased as proceeding of the network formation in the gel. The gels composed of long spacer monomer of DD or cubic cross-linking reagent of POSS showed higher intensity of the emission than the gels synthesized by HD or TMCTS. Only a slight increase of the emission intensity was observed in the gels containing anthracene, pelyrene, 9,10-diphenylanthracene.
