title: Novel inorganic-organic hybrid fluorescence chemosensor derived from SBA-15 for copper cation.
abstract: A novel mesoporous SBA-15 type of hybrid material (3-trimethoxysilylpropyl)[4-(2-hydroxyphenyl)methylene] benzenesulfonamide (Schiff-SBA-15) has been obtained by co-condensation of tetraethyl orthosilicate and the organosilane, and the result of XRD confirms the order hexagonal structure of the composite. This hybrid mesoporous material is fluorescent-active, exhibiting high selectivity for sensing Cu2+ in polar solution. The remarkable fluorescence quenching in emission spectrum upon the addition of Cu2+ is attributed to the intramolecular charge transfer after the formation of a coordinate complex of a large conjugate system and Cu2+ ions.
