Abstract

Abstract : The synthesis, structural and photophysical characterization, and theoretical study of tetranuclear copper(i ) cubane-type Cu4 I4 clusters with different 10-(aryl)phenoxarsine ligands are presented. Abstract : In this work, we present the synthesis, structural and photophysical characterization, and theoretical study of tetranuclear copper(i ) cubane-type Cu4 I4 clusters 6–10 with different 10-(aryl)phenoxarsine ligands – 10-( p -fluorophenyl)phenoxarsine (1 ), 10-( p -ethoxyphenyl)phenoxarsine (2 ), 10-(phenyl)phenoxarsine (3 ), 10-( m -fluorophenyl)phenoxarsine (4 ), and 10-( o -methoxyphenyl)phenoxarsine (5 ), respectively. The structures of 1–5 were confirmed by NMR spectroscopy, mass spectrometry, elemental analysis and for complexes 6, 7, and 10 by single-crystal X-ray diffraction analysis. The UV/Vis absorption and emission properties were studied and rationalized by DFT and time-dependent DFT calculations. In the solid state, under UV irradiation, all complexes exhibit an intense green emission, which was attributed to a cluster-centered triplet state.
