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 heavyatom in intersystem crossing processes. Mes=mesityl, THF=tetrahydrofuran
