Abstract

This paper deals with our recent work on the preparation of soluble ionic polysilsesquioxanes (PSQs) with regular structures, i.e. rod-like and ladder-like structures, by hydrolytic polycondensation (sol-gel reaction) of organotrialkoxysilanes containing functional groups, which changed to ionic groups, i.e. ammonium, carboxylate and sulfonate groups, during the reactions. In addition, we report on the preparation of ionic silsesquioxanes (SQs) with other structures, indicating characteristic properties, e.g. low-crystalline cage-like oligoSQ (POSS) and ionic liquid containing SQ framework, by hydrolytic condensation. Finally, the hybridization of an ammonium group-containing rod-like (ladder-like) PSQ with carbon nanotube and dye compounds, to approach to the functional materials, is described.
