摘要：
A novel polyhedral oligomeric silsesquioxane（POSS）-based organic-inorganic hybrid nanocomposite（EF-POSS） was prepared by Pt-catalyzed hydrosilylation reaction of octahydridosilsesquioxane（T;H;,POSS） with a luminescent substituted acetylene(2- ethynyl-7-(4-（4-methylstyryl）styryl)-9,9-dioctyl-9H-fluorene（EF）) in high yield.The hybrid nanocomposite was soluble in common solvents such as CH;Cl;,CHCl;,THF and 1,4-dioxane.Its structure and property were characterized by FTIR, NMR,TGA,UV and PL,respectively.The results show that the hybrid nanocomposite with high thermal stability emits stable blue light as a result of photo excitation and possesses high photoluminescence quantum efficiency(φ;).
