摘要
A highly luminescent supramolecular Cu2I2(NH3)(2)-sandwiched Cu-3(pyrazolate)(3) adduct was reported as a temperature sensor. The adduct is stabilized by the synergy of intermolecular Cu3I ( acidbase), CuCu and NH interactions, to form a Cu8I2 cluster. The emission intensity exhibits a temperature-dependent effect in the solid state with a sensitivity of -0.685% K-1. DFT and TDDFT calculations revealed that the luminescence originates from the triplet state of Cu8I2 cluster-centered charge transfer ((CC)-C-3).
