A 1D coordination polymer based on CuI and 2-(diphenylphosphino)pyrimidine: synthesis, structure and luminescent properties

Abstract

1-D chain coordination polymer (CP) of [Cu2I2(PymPPh2)]n type has been synthesized reacting CuI with 2-(diphenylphosphino)pyrimidine (PymPPh2) under mild conditions (MeCN, r.t.). The structure of the CP is imagined by double-stranded (Cu2I2)n ribbons, the Cu atoms of which are bridged by the PymPPh2 ligands in a 1,3-N,P fashion. At ambient temperature the solid-state CP manifests broad-band photoluminescence (λmax = 530 nm) with the average lifetime of 1.2 μs and quantum efficiency being 15%.
