Abstract

In this study, highly ordered Mesoporous silica material (SBA-15) functionalized with Diethyl 2-(9-fluorenyl) malonate as a flourophore is reported. The anchoring of flourophores to the hydroxyl group on SBA-15 surface was done with post synthesis method. The obtained materials were characterized by small and wide angle X-ray diffraction, N2 adsorption– desorption, Fourier transform infrared spectroscopy and thermogravimetric analysis that indicate the successful immobilization of Diethyl 2-(9-fluorenyl) malonate on the surface of Mesoporous silica. This organic– inorganic hybrid displayed highly selective and sensitive to Fe 3+ ion over other cations such as Mg 2+, Cr 3+, Co 2+, Ni 2+, Cu 2+, Hg 2+ and Zn 2+. Turn-off photoluminescence of this material was remarkably observed for iron ions in comparing of the other cations. A good linearity between the Fluorescence intensity of the prepared material and the concentration of Fe 3+ ion is constructed, which enables this martial as a Fluorescence chemo sensor for detecting the Fe 3+ ion with a suitable detection limit.
