Abstract

A novel, promising ligand for luminescent lanthanide complexes tris-((4-(3-methyl-1-phenyl-5-pyrazolonyl)-phenylmethylidene)-2-aminoethyl)amine (trenPMBP) was prepared and used as effective"antenna" for the ligand-sensitized photoluminescence of Tb3+, Dy3+ and Sm3+ ions. All the complexesshow surprisingly intensive photoluminescence in comparison with their simple 4-benzoyl-3-methyl-1-phenyl-5-pyrazolone analogues. One of the reasons of such result can be a relatively high located tripletenergy level of trenPMBP around 22675cm-1, which properly fits with the emissive energy levels ofTb3+ and Dy3+ (20430cm-1 and 20830cm-1, respectively), thus avoiding back-energy transfer from thelanthanide to the ligand.
