We report the synthesis, characterization, and photophysical properties of a series of rhenium(I) polypyridine maleimide complexes [Re(N-N)(CO)(3)(py-3-mal)](CF(3)SO(3)) [N-N = 1,10-phenanthroline, phen (1), 2,9-dimethyl-1,10-phenanthroline, 2,9-Me(2)-phen (2), 3,4,7,8-tetramethyl-1,10-phenanthroline, 3,4,7,8-Me(4)-phen (3), 4,7-diphenyl-1,10-phenanthroline, 4,7-Ph(2)-phen (4), 2,9-dimethyl-4,7-diphenyl-1
我们报告的合成,表征和一系列((I)聚吡啶马来酰亚胺配合物[Re(NN)(CO)(3)(py-3-mal)](CF(3)SO(3))的光物理性质[NN = 1,10-菲咯啉,phen(1),2,9-二甲基-1,10-菲咯啉,2,9-Me(2)-phen(2),3,4,7,8-四甲基- 1,10-菲咯啉,3,4,7,8-Me(4)-phen(3),4,7-二苯基-1,10-菲咯啉,4,7-Ph(2)-phen(4), 2,9-二甲基-4,7-二苯基-1,10-菲咯啉,2,9-Me(2)-4,7-Ph(2)-phen(5),2,2'-联喹啉,biq( 6); py-3-mal = N-(3-吡啶基)马来酰亚胺]。研究了配合物2的X射线晶体结构。激发后,络合物在298 K的流体溶液中显示出强烈且长寿命的光致发光。发射波长范围为514至654 nm,并且发射寿命降为微秒级。发光被指定为源自金属到配体的电荷转移MLCT
