利用电喷雾质谱（ESI-MS）对2，2'-联吡啶-4,4'-二羧酸乙酯与过渡金属铼的 系列配合物[（4,4'-(OOEt)_2-bpy)Re(CO)_3RPF_6] [其中bpy = 2,2'-联吡啶，R = 吡啶、4-甲基吡啶、4-羟基吡啶、4-氨基吡啶、10-（4-甲基吡啶基）吩噻嗪（ py-PTZ）进行分析，研究了配合物及其配体在不同源内CID(in-source collision induced dissociation, in-source CID)的相对稳定性。结果表明，随着源内 CID电压的升高，配合物中的配体R容易脱落并形成稳定的联吡啶三羰配位离子[(4, 4'(COOEt)_2-bpy)Re(CO)_3]~+。配体脱落从易到难的顺序为：吡啶 > 4-甲基吡啶 >-甲基吡啶>4-羟基吡啶>4-氨基吡啶>py-PTZ。

The electrospray ionization mass spectrometry (ESI-MS) of a series of rhenium (I) bipyridyl complexes [(4,4'-(COOEt)_2-bpy)Re(CO)_3RPF_6], where bpy is 2 2'-bipyridine and R is pyridine, 4-methylpyridine, 4- hydroxypyridine, 4-ammopyridine or 10-(4-picolyl) phenothiazine (py-PTZ ) was studied. The dissociation of the ligands (R) forms the fragment of [(4,4'-(C00Et)2-bpy) Re (CO)_3]~+ at different voltages of in- source collision induced dissociation (CED). The dissociation tendency is in an order: pyiidine> 4-methylpyridine > 4-hydroxypyridine > 4- aminopyridine > py-PTZ. It might be used to deduce the stability of these complexes when they are used as photosensitizers in solar cells.

Key words: ESI-MS;BIPYRIDINE P;CARBOXYLIC ACID ESTER;PYRIDINE P;THIOPHENE P, photosensitive dye
