| description | We present here the synthesis, chemical, and photophysical study of a series of three new copper halide derivatives, namely <b>2a</b>–<b>c</b>. They are all tetranuclear copper-iodide clusters of general formula [Cu(μ<sub>3</sub>-I)P]<sub>4</sub> consisting of a cubane-like {Cu<sub>4</sub>I<sub>4</sub>} motif and P = phosphine. They differ in the type of the phosphines used as ligands: a monophosphine with a single pendant ester unit (complex <b>2a</b>), two pendant ester units (<b>2b</b>), and a diphosphine containing two esters in the linker (<b>2c</b>). The molecular structure of the complexes was determined by single-crystal X-ray diffraction analysis. All the investigated derivatives were found to be photo- and thermally-stable luminescent species. In the solid state, the complexes display intense and long-lived photoluminescence in the orange region with PLQY values of 0.43–0.84 at room temperature associated mainly with a <sup>3</sup>CC excited state with mixed <sup>3</sup>XMCT character. |
