摘要：The carboxyl-terminated polysiloxane (CTP) was successfully synthesized from amine-terminated polysiloxane and succinic anhydride and characterized by the H-1 NMR and C-13 NMR spectroscopy. The complexes of lanthanide ions (Eu3+, Tb3+, and Dy3+) with CTP were prepared and show excellent fluorescence properties. Narrow-width red or green fluorescence was observed under UV irradiation, indicating the successful coordination and the presence of the intra-molecular energy transfer process. For the functionalized polysiloxane, the coordination number is hard to be confirmed due to polysiloxane excellent flexibility. In order to investigate the coordination number and structure of these products, the carboxyl-functionalized disiloxane (CFD) and luminescent materials on its basis (CFD-Ln) were synthesized and their coordination structure was confirmed by IR, fluorescence spectroscopy and XPS. Through the qualitative comparison between the CFD-Ln and CTP-Ln, the coordination structure of the CTP-Ln material was elucidated.
