Abstract
A new copper(I) heteroleptic pyridyl functionalized dithiocarbamate(dtc) complex, [Cu(L)2dppf]·2H2O·MeOH, (1) (where L = N-benzyl-N-methylpyridyldtc and dppf = = diphenyl phosphinoferrocene), has been synthesized from the reaction of [Cu2(μ-Br)2(k2-P,P-dppf)2] and dithiocarbamate ligand (L). The synthesized complex has been characterized by elemental analysis, spectroscopy techniques (IR, 1H, 13C, 31P NMR, and UV-Vis), and single-crystal X-ray crystallography. In this heteroleptic complex, the Cu atom forms distorted tetrahedral coordination geometry. The supramolecular architecture in the complex has been sustained in the solid phase by, C–H⋯O and C–H⋯π (chelate = CuS2C) interactions. The emission spectrum of the complex has been studied in DCM solution. The charge-transfer excited state is quenched due to intramolecular energy transfer from the {Cu(S,S)(P,P)} moiety to the ferrocene therefore dppf-based complex shows no detectable emission at room temperature. This complex is weakly conducting and exhibit semiconductor behavior at room temperature.
