摘要 : The reactions of Re(CO)_5X (X=Cl,Br) with 7-amino-2,4-dimethyl-1,8-naphthyridine (H_2L~1) and 7-[2-(6-chloropyridyl)-amino]-2,4-dimethyl-1,8-naphthyridine (H_2L~1) and 7-(2-(6-chloropyridyl)-amino]-2,4-dimethyl-1,8-naphthyrdylcarb... 展开 The reactions of Re(CO)_5X (X=Cl,Br) with 7-amino-2,4-dimethyl-1,8-naphthyridine (H_2L~1) and 7-[2-(6-chloropyridyl)-amino]-2,4-dimethyl-1,8-naphthyridine (H_2L~1) and 7-(2-(6-chloropyridyl)-amino]-2,4-dimethyl-1,8-naphthyrdylcarbamoyl complex [Re(CO)_4(HL~1CO)] (1) and the naphthyridylamido complex [Re(CO)_4(L~2)] (2),respectively.The structures of HL~2,1·CHCl-3,1·HL~3·2CH_2Cl_2 [HL~3=(7-chloronaphthyridyl)(5,7-dimethylnaphthyridyl)amine],and 2 have been determined by X-ray crystallography.Complex 1 displays a weak emission at 453 nmin an EtOH/MeOH (1:4,v/v0 glassy solution at 77K;complex 2 3xhibits an intense (quantum yield:0.22 in CH_2Cl_2) and long-lived emission (46mus in CH_2Cl_2),with a solvent-sensitive lambda_(max),in degassed solutions at rom temperature. 收起
