Synthesis of Mesoporous Organosilicate Films in Supercritical Carbon Dioxide

Uniform, well-ordered, mesoporous organosilicate films (see Figure) have been synthesized by efficient direct and post-synthesis functionalization methods in supercritical carbon dioxide and characterized using spectroscopic, microscopy, and diffraction techniques. These materials have numerous potential applications, including in sensors, low-k dielectrics, separations, and catalysis.
