Abstract

pH sensitive fluorescent sol-gels were obtained by both covalent immobilization of amino¯uorescein (AF) via isocyanate or epoxy groups, and by co-condensation of tetramethoxysilane (TMOS) and phenyltrimethoxysilane (Ph-TriMOS) in the presence of AF. The gel precursors were deposited on glass supports, cured, and characterized in terms of response to pH, pKa values, effects of ionic strength, ...
