“…(13,14). Our research team presently have done extensive work and realized six paths to construct the functional silylated precursors: amino group modification (15,16), carboxyl group modification (17), hydroxyl group modification (18–20), merocapto group modification (21,22), sulfonic groups modification (23), methylene modification (24,25). After the modification, these modified functional silylated precursors can be assembled with lanthanide ions and tetraethoxysilane (TEOS) to compose hybrid systems through coordination bond between it and Ln 3+ and the covalent bonds between it and Si–O network (15–26).…”

According to coordination chemistry principle and molecular assembly technology, series of ternary lanthanide centered hybrid systems have been constructed through coordination bonds. Among one component (ligand) is organically modified Si-O network, which originates from the functional molecular bridge (BFPPSi) by the functionalization of 1,3-bis(2-formylphenoxy)-2-propanol (BFPP) with 3-(triethoxysilyl)propyl isocyanate. In the second component (ligand), three different organic polymeric chains are introduced, poly-(methyl methacrylate) (PMMA, from the polymerization of MMA with the benzoyl peroxide [BPO] as the initiator), poly-(methyl acrylic acid) (PMAA, from the polymerization of MAA with the BPO as the initiator), polyvinyl pyridine, respectively. All these ternary hybrid materials show homogeneous, regular microstructure, suggesting the existence of assembly process of lanthanide centers, inorganic Si-O network and organic polymer chain. Compared to the binary hybrids without polymer chain, the photoluminescent properties of these ternary hybrids present stronger luminescent intensities, longer lifetimes and higher luminescent quantum efficiencies indicating that the introduction of organic polymer chain is favorable for the luminescence of the whole hybrid systems.

A series of ternary organic/inorganic/polymer hybrid materials have been assembled on the basis of the coordination chemistry principle. Mercapto‐functionalized MBA‐Si from MBA (4‐mercaptobenzoic acid) behaves as the first coordination unit, which forms sulfide linkages, resulting in an inorganic Si–O network after hydrolysis and copolycondensation with TEOS (tetraethoxysilane). The organic polymers PVPD [poly(4‐vinylpyridine)] and PMMA [poly(methyl methacrylate)] play a role of the second coordination unit, whose organic polymeric C–C chain originates from addition polymerization of the monomers 4‐VPD (4‐vinylpyridine) and MMA (methyl methacrylate), respectively. These hybrids are characterized in detail to compare with the binary hybrids without an organic polymer unit, whose results reveal that the microstructure, the thermal stability, and especially the photoluminescence properties of the hybrid system are improved with the introduction of the polymer as the coligand.
