The high affinity of Ag ions for aromatic π donors and cyano groups is exploited in a novel MALDI-TOF mass spectrometric method for the identification of hydrogen-bonded assemblies. The interaction with the Ag ions-which, for example, can be complexed by two phenyl groups in a sandwich-type manner (see drawing on the right)-provides positively charged assemblies in a nondestructive way.
银离子对芳香π供体和氰基具有高亲和力，这一特性被用于一种新型基质辅助激光解吸电离飞行时间质谱法（MALDI-TOF）中，以鉴定氢键组装体。与银离子的相互作用——例如，银离子可以以夹心型方式被两个苯基络合（见右图）——以非破坏性方式提供带正电荷的组装体。
