| 中文摘要 | heteroleptic neutral mononuclear cuprous complexes with dipyrrin derivatives and phosphine mixed-ligands including 1,3,7,9-tetramethyldipyrrin (1), 5-phenyl-1,3,7,9-tetramethyldipyrrin (2), 2,8-dibromo-1,3,7,9-tetramethyldipyrrin (3), 1,9-dichloro-5-phenyldipyrrin (4), 1,9-dibromo-5-phenyldipyrrin (5), 5-pentafluorophenyl-1,3,7,9-tetramethyldipyrrin (6) and 1,5,9-triphenyldipyrrin (7) have been synthesized and fully characterized. the central cu(i) atoms of these complexes in general formulas of cu(1-6)-(pph3)(2) (1a-6a) and cu(1-6)(dpephos) (1b-6b) [dpephos = bis(2-diphenylphosphinophenyl)ether] all exhibit a pseudo-tetrahedral geometry, while complex cu(7)(pph3) (7a) is tricoordinated in a pyramidal conformation due to the large steric hindrance of ligand 7. the oxidation potentials assigned to oxidations of cu(i)-cu(ii) are extraordinarily low in the range of 0.36-1.02 v vs. ag/agcl compared with traditional [cu(phen)(pp)](+) analogues. their emission maxima range from 495 to 595 nm in dichloromethane at room temperature with quantum yields of 0.05-4.03% and lifetimes on the order of nanoseconds. unlike the characteristic mlct emission in cationic cu(i) complexes, the emissions are assigned to the dipyrrin-centered intraligand charge transition (ilct) based on the fact that the increased conjugation within the dipyrrinato anion leads to a weaker metal-ligand interaction, thus preventing the mixing of pi orbitals of ligand and 3d orbitals of cu(i) atom. this conclusion is also supported by electrochemical data and theoretical calculations. |
