新型 MALDI-TOF 质谱方法利用 Ag+ 离子对芳香族 π 供体和氰基的高亲和力来鉴定氢键组装体。与 Ag+ 离子的相互作用（例如，可以通过两个苯基以夹心方式络合（见右图））以非破坏性方式提供带正电的组装体。
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.
