Abstract:

A functional molecular bridge (named as HBA-TEPIC) (HBA = 1,4-hydroxybenzoic acid, TEPIC = 3-(triethoxysilyl)-propyl-isocyanate) was achieved through the hydrogen transfer nucleophilic addition reaction. Firstly, the molecular precursors coordinate to lanthanide ions (Eu3+ and Tb3+) and then form the covalently bonded Si-O network to obtain the polymeric hybrid material (HBA-TEPIC-RE). Secondly, the synthesized polymers PMMA and PMAALM and commercial PVP (polyvinylpyrrolidone) were further introduced into the inorganic network to obtain hybrids with the organic chains and inorganic networks together (HBA-TEPIC-RE-PVP/PMAA/PMAALM). The regular microstructure indicates that a self-assembly system exists and both lanthanide ions and polymeric chains have an influence on the growth tendency of the hybrids. The results of the luminescent properties of the hybrids prove that the HBA-TEPIC-Eu-PVP hybrid represents the longest lifetime and highest quantum efficiency.
