【Abstract】

A new tetranuclear cuprous halide complex,(CuBr)_4(PN)_(2 )(PN=2-(diphenylphosphaneyl)-6-methoxypyridine),was synthesized and fully characterized.In solid state,this complex exhibits efficient blue emission with a photoluminescence quantum yield of 43.3%and a decay time of 19μs at room temperature.The theoretical calculations,combined with the temperature dependence of spectroscopic properties and emission decay behaviors,indicate that the emission in the solid state originates from the ~(1,3)(MLCT+XLCT) excited states,which are in thermal equilibrium with a small energy gap of about 0.1 eV.
