We report the synthesis, characterization, and photophysical and electrochemical properties of four bifunctional luminescent rhenium(I) complexes that contain an extended planar diimine ligand and a biotin moiety, [Re(N-N)(CO)3(L)](PF6) (N-N = dipyrido[3,2-a:2‘,3‘-c]phenazine, dppz; L = 4-((biotinamido)methyl)pyridine (py-CH2NH-biotin; 1), 4-(N-((6-biotinamido)hexanoyl)aminomethyl)pyridine, (py-CH
我们报告的合成,表征,以及包含扩展的平面二亚胺配体和生物素部分,[Re(NN)(CO)3(L)](PF 6)的四个双功能发光rh(I)配合物的光物理和电化学性质。(NN =二吡啶基[3,2- a:2',3'- c ]吩嗪,dppz; L = 4-((biotinamido)methyl)吡啶(py-CH 2 NH-biotin; 1),4-(N -((6-生物素亚氨基)己酰基)氨基甲基)吡啶,(py-CH 2 NHCOC 5 H 10 NH-生物素;2); NN =苯并[ i ]双吡啶并[3,2- a:2',3'- c吩嗪,dppn; L = py-CH 2 NH-生物素(3),py-CH 2 NHCOC 5 H 10 NH-生物素(4))。在照射时,复合物1 - 4表现出强烈的和长寿命的发射中在298K脱氧流体溶液和低温玻璃。发光被分配给三重态配体(3 IL)(π→π*)(二亚胺)激发态
