Formation of complexes between macrocyclic diamines and primary ammonium thiocyanates: dependence of binding upon host structure

Abstract

The series of macrocyclic diamines (3b) and (4b) form complexes with primary alkylammonium thiocyanates with free energies of binding that depend upon ring size; the diamines (7) and (8) with functional groups in the side chains are readily synthesized and form strong complexes with polyfunctional ammonium thiocyanates.
