Squarely mesoporous and functional nanocomposites by self-directed assembly of organosilane

This work reports the first example to synthesize squarely mesoporous and functional nanocomposites by self-directed assembly of porphyrin-bridged silsesquioxane. Due to the formation of robust silica networks around conjugated porphyrin moieties, the resultant mesoporous materials exhibit excellent optoelectronic properties and good thermal stability, providing unique platforms for many applications.
