Photoactive ternary inorganic/organic hybrids of Al3+, Zn2+ center/8-hydroxyquinoline functionalized Si–O network/polymer chain
چکیده انگلیسی

A novel series of metallic (Al, Zn) centered inorganic Si–O network/polymer hybrid materials have been constructed. Among functional linkage HQSi is achieved from the modification of 8-hydroxyquinoline (HQ) by 3-(triethoxysilyl)-propyl isocyanate (TESPIC) and used to covalently bonding Si–O network. Poly-(methyl methacrylate) (PMMA) or poly-(methacrylic acid) (PMAA) is introduced by the polymerization of methyl methacrylate (MMA) or methacrylic acid (MAA), respectively. Both inorganic Si–O network and polymer chain are coordinated to some metal ions (Al3+, Zn2+), resulting in the ternary luminescent hybrid material systems (abbreviated as HQ–Si–M–PMMA(PMAA), M = Al, Zn). The physical characterization and especially the photoluminescence property of them are studied in detail, which present the regular microstructure and green photoluminescence originated from the photoactive modified HQ functional unit by the perturbation of metallic ions (Al3+, Zn2+).
