Luminescent Cu(I) complexes have drawn considerable attention as alternative materials to precious transition metal due their low cost and electron configuration. Discrete heteroleptic diamine-diphosphine copper(I) been investigated owing outstanding photophysical features. However, coordination polymers remain mostly unexplored. Herein, we report the synthesis characterization of a polymer by employing bidentate oxybis(2,1-phenylene)bis(diphenylphosphine) (POP) diphosphine nitrogen heterocyclic 5-[4-(1-imidazolyl)phenyl]-2H-tetrazole (ipt) ligands. By utilizing mixed-solvent strategy, one-dimensional (1D) linear chain was constructed under solvothermal reaction conditions. Temperature-dependent emission spectra combined with decay time measurements demonstrate that originated from triplet phosphorescence at ambient temperature.
