Title
Molecular assembly, physical characterization and photophysical properties of ternary lanthanide hybrids containing functional 1,2,4-triazole and 1,10-phenanthroline
Abstract

This work focuses on the preparation and the study of the luminescence properties of series ternary lanthanide molecular hybrid materials. We selected 1,10-phenanthroline as a second ligand to introduce into the binary hybrid system in which an organic functional compound 1,2,4-triazole was included. The further investigation of the luminescence properties proves that, after the addition of the 1,10-phenanthroline, the energy levels matching degree between the organic segments and RE ions is more suited and appropriate so that the final ternary hybrid materials show stronger luminescence intensity, which substantiating that the heterocyclic ligand would become the main energy donor and has the possibility to sensitize Ln3+ ions via an intramolecular energy transfer process, at the same time, the luminescent quantum efficiencies of the ternary systems are also highly improved compared with the binary systems. Besides, the introduction of the second ligands don’t change the disorder structure of the siliceous skeleton and thus no phase separation be observed in the hybrid systems. We may expect to obtain stable and efficient hybrid materials in optical or electronic areas from this method.
