applying photocatalytic systems to activate substrates becomes increasingly popular. Although photosensitizers serve as the core of the photocatalytic reaction, the design of a photosensitizer has not been taken for granted. By modifying ligands of organometallic complexes to optimize properties of photosensitizers, we successfully achieved a series of iridium complexes with long excited triplet-state lifetime
处于激发态的底物与相应的基态显着不同,因此它们被视为具有不同物理性质和
化学反应性的不同
化学物种。因此,将光催化系统用于活化基材变得越来越普遍。尽管光敏剂是光催化反应的核心,但是光敏剂的设计并不是理所当然的。通过修饰有机
金属配合物的
配体以优化光敏剂的性能,我们成功实现了一系列
铱配合物,具有长激发三重态寿命,高三重激发态能量,强吸收性和鲁棒稳定性。评估了制备的
铱配合物作为光敏剂对各种挑战性的光环加成反应(例如,
