Octadiphenylsulfonylsilsesquioxane (ODPSS) was synthesized through sulfonylation of octaphenylsilsesquioxane (OPS) with benzenesulfonyl chloride and the AlCl3 catalyst in dichloromethane (CH2Cl2). By changing the solvent, catalyst, reaction time and molar ratio of reactants, the optimal reaction conditions were determined. It was found that OPS could be completely converted to ODPSS with a high yield. The product ODPSS was identified by FTIR, MALDI-TOF MS, 1H NMR, 13C NMR, 29Si NMR and elemental analysis. The reaction mechanism was analyzed and a sulfonylation model of OPS was established.
