Synthesis, Characterization of A Novel Polymeric Reaction Monomer for Preparing Highly Fluorescent Rare Earth Polymer Materials
A novel polymeric reaction monomer (NPRM) for preparing highly fluorescent rare earth polymer materials was synthesized via interface and coordinating reaction. The composition and structure of the NPRM and intermediate product (ligand) were characterized through the Fourier transform infrared spectroscopy (FT-IR), carbon-nuclear magnetic resonance spectrum (<13>CNMR), Mass spectra (MS), and element analysis data. The results showed that the composition and structure of NPRM agreed with that of anticipated product. The NPRM was composed of two important sections. Section 1 was able to provide excellent fluorescent properties for final rare earth polymer material through the effect energy transfer between ligand and rare earth ion; Section 2 would endow with the NPRM excellent polymeric active and form highly fluorescent rare earth polymer material. Fluorescent properties of the NPRM were also researched via a CARY ECLIPSE fluorescent spectrometer. The results showed that the NPRM possessed excellent luminescent properties. The corresponding emission peaks based on the <5>D<,0>→ <7>F<,1>(601.6nm), <5>D<,0>→<7>F<,2>(625.0nm), <5>D<,0>→<7>F<,3>(660.5nm) and <5>D<,0>→<7>F<,4> (706.3nm) transitions for Eu<3+> were observed. The strongest emission peak was at 625nm, which belonged to <5>D<,0>→<7>F<,2> transition.
