摘要

When the amide-containing receptor 1~+ is in a solution of dimethyl sulfoxide(DMSO)in the presence of basic anions(CH_3COO ,F~,H_2P(V),it undergoes deprotonation of the-NH fragment to give the corresponding zwitterion,which can be isolated as a crystalline solid.In the presence of less basic anions(Cr,Br ,NO_3~),1~+ establishes true hydrogen-bond interactions of decreasing intensity.The less acidic receptor 2~+ undergoes neat proton transfer with only the more basic anions CH_3COO~-and F~-,and establishes hydrogen-bond interactions with H_2PO_4~-.An empirical criterion for discerning neutralisation and hydrogen bonding,based on UV/Vis and ~1H NMR spectra,is proposed.
