以多官能环硅氧烷、1，3，5，7-四甲基环四硅氧烷(TMCTS)或立方倍半硅氧烷(1，3，5，7，9，11，13，15-octakis(dimethylsilyloxy)pentacyclo-[9，5，1，1，1，1]octasilsesquioxane，POSS)为交联剂，1，5-己二烯(HD)或1，9-癸二烯(DD)为间隔单体，在甲苯中进行光氢硅氢化反应，合成了含荧光分子的有机-无机杂化凝胶。含Py的凝胶比含Py的甲苯溶液显示出更高的发射强度。随着网络在凝胶中的形成，Py的发射强度增加。由长间隔单体DD或立方交联剂POSS组成的凝胶显示出比HD或TMCTS合成的凝胶更强的发射强度。结果表明，在含有9，10-二苯基、9，10-二苯基、9，10-二苯基、菲、菲的凝胶中，荧光强度略有增加。
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.
