Hexylene-bridged polysilsesquioxanes are hybrid organic-inorganic materials prepared by the sol-gel polymerization of 1,6-bis(trimethoxysilyl)hexane monomer 1. Previous studies showed that high surface area xerogels could be prepared from 2 with base catalyzed polymerizations while non-porous xerogels could be prepared with acidic catalysts. However, these xerogels were obtained from gels that had been aged for two weeks. The object of this study was to ascertain the influences of aging time (3, 7, 14, 28, 42, and 56 days) on the properties of the resulting xerogels.
