Factors affecting the efficiency of excited-states interactions of complexes between some visible light-emitting lanthanide ions and cyclophanes containing spirobiindanol phosphonates

Abstract

The efficiency of excited-states interactions between lanthanide ions Tb 3+ and Eu 3+ and some new cyclophanes (I, II, and III) has been studied in different media. High luminescence quantum yield values for terbium and europium complexes in DMSO and PMMA were obtained. The photophysical properties of the green and red emissive Tb 3+ and Eu 3+ complexes have been elucidated, respectively.
