Abstract
Organic–inorganic polymer hybrids were prepared utilizing the CH/π interactions. The sol–gel reaction of alkoxysilanes such as tetramethoxysilane (TMOS), methyltrimethoxysilane (MeTMOS), and phenyltrimethoxysilane (PhTMOS) was carried out in the presence of the polymer having the activated CH groups such as poly(vinyl chloride) (PVC). It was found that the transparent and homogeneous polymer hybrid was obtained from PVC and the alkoxysilane having aromatic groups such as PhTMOS. The transparent and homogeneous polymer hybrids could be obtained in a wide range of mass ratios (PVC/PhSiO1.5 = 9/1–3/7). In these polymer hybrids, the CH/π interaction was found to act as an important role for the dispersion of PVC in the silica matrix.
