Structural characterization and luminescence properties of trigonal Cu(i) iodine/bromine complexes comprising cation–π interactions

Abstract

Three-coordinate mononuclear copper(I) halide complexes (1 (I) and 2 (Br)), which bear a novel rigid diphosphine ligand derived from a benzimidazole skeleton, were prepared and characterized. Structural analyses of 1...

Metal–Organic Framework Based Thermoluminescence Dosimeter

“…The strong yellow fluorescence at 553 nm of SCU-300 should be attributed to the n*-π transitions of the ligand . This suggests that the ligand plays a major role in determining the HOMO/LOMO energy levels and that the redshift is attributable to the heavy atom effect. , The fluorescence decay curve of SCU-300, which has a decay time of 0.96 ns (Figure S9), demonstrates its potential for a higher reliability and lower measurement error in the dosimeter compared to LiF:Mg,Cu,P with a fluorescence decay time of 60 μs . The high photoluminescence quantum yield (70.66%) exhibited by SCU-300 suggests its potential for effectively reducing signal loss in the process of radiation detection (Figure S10).…”
