摘要

Abstract A series of pyridyl guanidinium–carboxylates has been prepared and the dimeric self-assembly of these studied in H 2 O/DMSO mixtures, principally using dilution isothermal calorimetry. Compounds 5 and 6, incorporating an aromatic ring in the “tethering” region between the guanidinium and carboxylate groups, demonstrate the strongest dimerisation in neat DMSO. X-ray crystal structures of 5 and 6 reveal two different dimerisation ...
