| 摘 要： | 利用电喷雾质谱(ESI-MS)的源内CID(in-source Collision Induced Degradation，in-source CID)对2，2‘-联吡啶-4，4‘-二羧酸乙酯与铼络合染料(化合物1)和钌络合染料(化合物2)进行研究，表征了络合物及其配体的相对稳定性结果表明。随CID电压的升高，化合物1的吡啶配体容易脱落．并形成稳定的联吡啶三羰基配位离子(4，4‘-(COOEt)2-bpy)Re(CO)3]^ ;而化合物2在较高的CID电压下会发生联吡啶环上取代基的中性丢失，其单电荷离子比二价电荷离子稳定。

| Abstract: | The ESI-MS spectra of compound 1 ((4,4'-(COOEt)_2-bpy) Re(CO)_3pyPF_6] )and 2 (Ru(bpy)_2(4,4'-(COOEt)_2-bpy)2PF_6]) were studied under different in-source CID fragmentation. The stability of the compounds and their ligands was characterized. The Experimental results showd that the pyridyl ligand in compound 1 dissociated easily to become (4,4'-(COOEt)_2-bpy)Re(CO)_3]~+ with the increase of CID fragmentation. The substituted group on the bipyridyl ligand in compound 2 lost C_2H_4 neutral molecule under a higher CID fragmentation (such as CID 110 V), and its single charge ion was more stable than its double charge ion. |
