Viedma Ripening of Chiral Coordination Polymers Based on Achiral Molecules

Abstract

When the chiral coordination polymers were composed of achiral molecules, the deracemization of the bulk product remains a great challenge if without any chiral induction. The Viedma ripening theory was adopted herein to help the achievement of mirror symmetry breaking for the bulk chirality of two chiral coordination polymers. The enantiomeric excess of the bulk chirality for the first compound is about 100%, which means absolute asymmetric synthesis. The deracemization degree of the bulk chirality for the second compound fluctuates occasionally. Further study has discussed the different deracemization degree of the bulk chirality for two compounds with the consideration of enantioselective incorporation in crystal cluster.
