Abstract

A top-down/bottom-up approach has been developed to fabricate mesoporous silica with well-aligned mesochannels of controlled orientation by means of cooperative assembly of an amphiphilic tri-block copolymer (P123) and silica species within lithographically designed confined nanospaces. Some mesochannel patterns that can be prepared by this technique are shown schematically in the picture. TEOS = tetraethoxysilane. (Figure Presented).
