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

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