Title:
Surprises in the Design of Anion Receptors:  Calorimetry Prevents False Reasoning
https://pubs.acs.org/na101/home/literatum/publisher/achs/journals/content/orlef7/2005/orlef7.2005.7.issue-15/ol051109k/production/images/large/ol051109kn00001.jpeg
Description:
Supplementing bicyclic guanidinium anion receptors with four sec-carboxamido groups leads to enhanced affinity for oxoanions, however, for a different reason than originally planned. Calorimetric analysis reveals that better binding is due to higher association entropies rather than more negative enthalpies. Thus, molecular design following geometric and functional complementarity principles may misguide supramolecular constructions aimed at a unique host−guest binding mode, as required, e.g., by self-assembly or catalysis.
