A series of nitrogen ligand (L)/copper complexes of the type [Cu(I)L](+), [Cu(II)L(X)](+) and [Cu(I)L(2)](+) (X = Cl(-), BF(4) (-), acac(-), CH(3)COO(-) and SO(3)CF(3) (-)) was studied in the gas phase by electrospray ionization mass spectrometry. The following ligands (L) were employed: 1,12-diazaperylene (dap), 1,1'-bisisoquinoline (bis), 2,2'-bipyridine (bpy), 1,10-phenanthroline (phen), 2,11-disubstituted
[Cu(I)L](+),[Cu(II)L(X)](+)和[Cu(I)L(2)]()的一系列氮配体(L)/铜配合物+)(X = Cl(-),BF(4)(-),acac(-),CH(3)COO(-)和SO(3)CF(3)(-))已在气相中进行了研究通过电喷雾电离质谱。使用以下配体(L):1,12-二氮杂萘(dap),1,1'-双异喹啉(bis),2,2'-联吡啶(bpy),1,10-菲咯啉(phen),2,11 -二取代的1,12-二氮杂戊环(dap),3,3'-二取代的1,1'-双异喹啉(双),5,8-二甲氧基取代的二氮杂戊环(meodap),6,6'-二甲氧基取代的二异喹啉(meobis )和2,9-二甲基-1,10-菲咯啉(dmphen)。碰撞诱导的分解测量用于评估不同铜络合物的相对稳定性。配体空间排列的影响,考察了络合所用的铜盐的取代基类型和抗衡离子的分子量。发现在溶液中[ML(2)]
