Description
Summary:In this paper, a neutral copper iodide hybrid with unique Cu 3 I 3 trimeric inorganic functional unit is successfully fabricated using 5,6,7,8‐tetrahydroquinoxaline ( L ) with large steric‐hindrance group as the organic ligand. The hybrid owns a one‐dimensional (1D) extended polymeric structure in the form of Cu 3 I 3 ( L ) 2 . As a CuI‐based hybrid, 1D‐Cu 3 I 3 ( L ) 2 has an infrequent far‐red/near‐infrared emission, exhibiting the potential application prospects in the field of display and night vision. Moreover, the luminescence mechanism is carefully studied by decay lifetime measurement and calculation of density of states, which is verified to be the combination of metal‐to‐ligand charge transfer and halide‐to‐ligand charge transfer.
