报道了一种高发光的超分子Cu_2I_2（NH_3）_2-夹心Cu_3（pyrazolate）_3加合物作为温度传感器。该加合物是通过分子间的Cu 3 + I（π酸+碱）、Cu + Cu和N + H相互作用的协同作用而稳定的，以形成Cu 8I 2簇合物。发射强度在固态下表现出温度依赖性效应，灵敏度为-0.685%K −1。DFT和TDDFT计算表明，发光源自Cu 8 I2团簇中心电荷转移（3CC）的三重态。
A highly luminescent supramolecular Cu2I2(NH3)2-sandwiched Cu3(pyrazolate)3 adduct was reported as a temperature sensor. The adduct is stabilized by the synergy of intermolecular Cu3⋯I (π acid⋯base), Cu⋯Cu and N⋯H 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 (3CC).
