The influence of pH over topography and spectroscopic properties of silica hybrid materials embedding meso-tetratolylporphyrin (original) (raw)

Materials Research Bulletin, 2009

Abstract

Hybrid porphyrin–silica materials consisting in 5,10,15,20-tetratolyl-21H,23H-porphine, encapsulated in silica matrices were obtained by sol–gel method. The hydrolysis and condensation reactions were performed by using tetraethylorthosilicate as precursor, either in one-step acid or in ...
