Efficient luminescence from easily prepared three-coordinate copper(i) arylamidophosphines

A series of brightly luminescent, three-coordinate copper(I) arylamidophosphine complexes have been prepared from readily available precursors in high yield. Emission maxima span 102 nm in the visible spectrum from 461 (blue) to 563 nm (yellow) while photoluminescence quantum yields range from 0.11 to 0.24 in fluid solution at room temperature.
