摘要: A series of oxadiazole-containing molecular hybrid materials with different structures (H1–H5) are controllably prepared by a hydrosilylation method based on the octahydridosilsesquioxane (POSS, T88HH). All these resultant soluble in common organic solvents, such as chloroform, toluene, tetrahydrofuran, and 1,2-dichloroethane, possess good film-forming properties. Their structure properties characterized evaluated FTIR, 1H NMR, 29Si GPC, TGA, DSC, UV-vis, PL, CV, elemental analysis, respectively. It is found that reaction almost proceeds quantitatively when feed ratio (molar number monomer to molar POSS) less than 4, at which hybrids can be varying ratio. These high thermal stability electron injecting an intense blue emission was observed hybrids. Simultaneously, it (H3–H5) strong π conjugation effect between POSS oxadiazole moiety show higher stability, better more those (H1 H2) without moiety.
