Luminescence of Dimeric T1(I) Complexes: Metal-Metal Interaction in the Electronically Excited State

Abstract

Dimeric diethyldithiocarbamatethallium(I) [Et 2NCS2Tl]2 shows a red emission at λmax=608 nm which undergoes a huge Stokes shift with regard to the excitation maximum at λ=246 nm. It is suggested that the emission originates from a sp excited state which is characterized by strong metal-metal bonding.
