Anomalous structure-luminescence relationship in phosphorescent gold(I)isonitrile neutral complexes

摘要

A new compound that exhibits the shortest intermolecular Au...Au distance ever reported for neutral RNCAuX complexes is found to exhibit a counterintuitive higher-energy Au-centered phosphorescence than that in an analogous compound with a much longer Au...Au distance,presumably due to a different extent of excited-state distortion in dimers vs.extended chains.
