Abstract

Abstract: Physical adsorption of various metal complexes including multinuclear heterometallic species onto polymethylsilsesquioxane (PMSQ) aerogel afforded their highly transparent mesoporous hybrids. One of the fabricated materials containing Ru(II) tris‐phenanthroline complexRuPhen3 −OH (RuPhen3 −OH @PMSQ) exhibited a photocatalytic activity for the dehydrogenation of the Hantzsch 1, 4‐dihydropyridine1H2, which was close to that observed for the corresponding homogeneous system. The photocatalytic activity ofRuPhen3 −OH @PMSQ was superior than that ofRuPhen3 −OH on other silica gels having larger or smaller pores, suggesting that the pore size of the PMSQ aerogel plays an important role for the high photocatalytic activity by allowing both the light and substrates to easily access the catalysts located at the inner space of the material. Abstract : Lighting it softly : Soft post‐modification of polymethylsilsesquioxane (PMSQ) aerogel with metal complexes has proven to afford highly active photocatalysts.
