The luminescent studies of cyclometalated Ir(III) complexes have attracted considerable interests in recent years. To fulfill the needs of emission wavelengths in various areas, the strategic emission color tuning of iridium(III) complexes is vital for their applications as phosphorescent materials. However, a feasible color-tuning method for iridacycles with fused carbon-rings (C^∧C) has not been reported yet. Herein, a convenient color-tuning strategy for C^∧C-based Iridacycles is accomplished with the aid of DFT calculations. The developed synthetic protocol allowed facile modifications on C^∧C units and N^∧N units via a one-pot synthesis starting from iridium vinyl complexes, accessing the novel phosphorescent iridapolycycles [(N^∧N)Ir(C^∧C)ClPPh₃]⁺.

颜色调整策略Iridapolycycles [（N ^∧ N）的Ir（C ^∧ C）ClPPh ₃ ] ⁺通过在这两个C中的协同修改^∧ C和N ^∧ n单元

近年来，环金属化的Ir（III）配合物的发光研究吸引了相当大的兴趣。为了满足各个领域中发射波长的需求，铱（III）配合物的策略性发射颜色调节对于它们作为磷光材料的应用至关重要。然而，对于具有稠合的碳环iridacycles一个可行颜色调整方法（C ^∧ C）还没有被报道。在此，对于C方便的颜色调整战略^∧基于C-Iridacycles与DFT计算的帮助下完成的。发达合成协议允许基于C容易修改^∧ C单位和N ^∧ N个单位通过一锅合成从铱络合物乙烯开始，接入新型磷光iridapolycycles [（N^∧ N）的Ir（C ^∧ C）ClPPh ₃ ] ⁺。
