A novel AlQ 3-functionalized SBA-15 mesoporous material was synthesized by using a modified organosilane as precursor and its emission spectra was studied. [Display omitted] ► Synthesis a modified precursor in which 8-HQ is attached to the APTES via a stable sulfonamide bond. ► Synthesis a new 8-HQ functionalized SBA-15 type material. ► Grafting of AlQ 3 complex to this new 8-HQ functionalized SBA-15 type material. ► Grafted AlQ 3 in prepared material displays blue shift in comparison with AlQ 3 complex in solution. ► The emission of grafted AlQ 3 can be tuned by using appropriate substitution on 8-HQ. A novel functionalized SBA-15 mesoporous material was prepared through co-condensation of tetraethylorthosilicate with an 8-hydroxyquinoline-5-sulfonamide-modified organosilane precursor in the presence of P123 as structure-directing agent. After removal of template, the obtained material was characterized by powder X-ray diffraction (XRD), nitrogen adsorption–desorption, Fourier transform infrared (FT-IR), thermal analysis (TGA–DTA), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and elemental analysis. Then, aluminum quinolate complex was attached covalently to this functionalized SBA-15 by using coordinating ability of grafted 8-HQ and its emission spectra showed a slightly blue shift in comparison with AlQ 3 complex.
