The new hybrid copper(I) iodide cluster (DBA)₄Cu₄I₄ enables ultra-bright triplet yellow-orange emission with a PLQY>94.9 % by the coaction of excited state structure reorganization and the metallophilicity interaction, and the phonon-assisted de-trapping process of exciton induces the negative thermal quenching effect at 80–300 K. Our investigation shows that this material has a great potential in practical X-ray imaging applications.
