Facile Synthesis of Functional Alkoxysilane Precursor with Short Linkers toward Organosilica Hybrids with a High Density of Chromophores

Abstract Tetraphenylpyrene (TPPy)-bridged alkoxysilane precursors with short linkers were synthesized by development of a facile synthetic route, and sol–gel polymerized to transparent organosilica films which showed higher absoption coefficient than the conventional route due to dense accumulation of TPPy units in the films.
