with approximately one to six 6-N,N-dimethylamino-2-naphthoic acid (DMANA) groups through the appropriate alkyl linkers, exhibited remarkably long-emission lifetimes of up to 216 μs in DMSO/H2O at room temperature through a reversible electronic energy transfer effect between the Ir complex core and the organic chromophore moieties; however, under the same conditions, the lifetime of fac-Ir(tpy)3 was
我们报告的设计和合成的三环金属化铱(Ir)配合物,在二氨基接头的末端含有芳氧基,这些化合物表现出特别长的发射寿命,并且是由fac-tris-homoeptic环金属化Ir配合物的区域选择性取代反应制备,fac-Ir(tpy)3(tpy = 2-(4'-甲苯基)吡啶)。发现通过适当的烷基接头配备约一到六个6-N,N-二甲基氨基-2-萘甲酸(DMANA)基团的Ir(tpy)3络合物具有高达216的显着长发射寿命通过Ir复合核与有机生色团部分之间可逆的电子能量转移效应,室温下DMSO / H2O中的μs;但是,在相同条件下,fac-Ir(tpy)3的寿命为1.4μs。关于机械方面,
