Host-guest chemistry using an oriented mesoporous host: alignment and isolation of a semiconducting polymer in the nanopores of an ordered silica matrix
Article Abstract:
A study was conducted to analyze the preparation of oriented polymer/silica composites by integrating the conjugated semiconducting polymer MEH-PPV into the pores of an aligned, hexagonally ordered mesoporous silica. The photophysics of isolated, oriented semiconducting polymers were also examined. The resulting polymer incorporation was observed by polarized photoluminescence spectroscopy.

Effect of framework polymerization on the phase stability of periodic silica/surfactant nanostructured composites
Article Abstract:
It has been established that synthesis pH affects the phase stability of silica/surfactant composite materials under hydrothermal conditions. Lower synthesis pH leads to a mesophase with a more polymerized structure.
