Abstract
Alignment control of pores in phenylene-bridged mesoporous organosilica thin films was achieved using a substrate coated with a rubbing-treated polyimide film.
The films are prepared by two different methods; hydrothermal deposition and so-called evaporation-induced self-assembly (EISA). The narrow alignment distribution of mesochannels
is achieved by the interfacial hydrophobic interactions between alkyl chains of surfactant and the elongated polymer chains of rubbing-treated polyimide. The molecular-scale ordering of
the framework in the films is low, unlike those in mesoporous organosilica powders prepared under basic conditions.
