Notes:
In this paper, diphenyl-silsesquioxane was synthesized and characterized. Firstly,octa-isobutyl silsesquioxane endo-disilanol (OIBS-EDN) containing two Si-OH functions wasformed by base-catalyzed cleavage of octa-isobutyl silsesquioxane (OIBS). Then, oligomericsilsesquioxane containing two phenyl functions (DPS) was prepared by addingdiphenyldichlorosilane to the solution of OIBS-EDN in right proportion with the presence oftrithylamine in THF. The products were characterized by FTIR, 1HNMR, 13CNMR, 29SiNMR, X-raydiffraction, EA, DSC and GPC respectively. The results show that difunctional POSS with clearstructure and high yield can be prepared by this process. And a new simple and feasible approach todesign and synthesize difunctional POSS was put forward
