Synthesis, X-ray crystal structure and photophysical properties of tris(dibenzoylmethanido)(1,10-phenanthroline)samarium(III)

摘要

Herein we report for the first time the complete characterization and photophysical properties of tris(dibenzoylmethanido)(1,10-phenanthroline) samarium(III) (Sm(DBM)_3phen) in the absence of a polymer matrix. The solid state structure of Sm(DBM)_3phen has been determined by single-crystal X-ray crystallography and shows the geometry of the local coordination environment around the samarium(III) ion to be a slightly distorted square antiprism. The absolute quantum yield and luminescence lifetime were measured as 0.86 ± 0.40% and 41 ± 2 μs, respectively.
