摘要：

A series of polynuclear copper(I) and gold(I) acetylides and tetranuclear copper(I) and silver(I) chalcogenides has been synthesized and shown to exhibit rich photoluminescence behaviour at room temperature. The phosphorescent states of the complexes undergo facile oxidative electron transfer quenching reactions with one-electron pyridinium accepters and are strong reducing agents in the excited state. An LMCT/d-s mixed state is suggested to be responsible for the low-energy emission. (C) 1997 Elsevier Science S.A.
