New silica-based hybrid organic–inorganic solids containing oligoarylene-vinylene fluorophore-terminated phosphonates†
Abstract
Cogelation of new trimethoxysilane-derived oligoarylene-vinylene fluorophores terminated with diethyl and di-tert-butyl phosphonates is described. Materials were analyzed by solid state NMR techniques and BET. Fluorescence proves to be a very sensitive method to detect the chromophore and to obtain information about the organization inside the solid.
