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.
