Abstract

Heavy-metal light show: Photophysical studies show unprecedented high fluorescence quantum yields (Φf up to 69%, τf≈ 1-3 ns) and unexpectedly slow intersystem crossing for a series of rhodium complexes. This new class of compounds challenges our understanding of the behavior of excited electronic states and the role of the heavy atom in intersystem crossing processes. Mes = mesityl, THF = tetrahydrofuran, Tol = toluene. (Figure Presented).
