Abstract

This paper describes a new class of homochiral salen-based infinite coordination polymers (ICPs) and the discovery of a novel and pseudo-reversible solvent-induced crystallization process. The solvent, methanol in this case, induces such a transformation through a change in the coordination environment around the metal bridging the metallo-salen portion of the complex. This transformation has allowed us to use X-ray methods to structurally characterize the crystalline product and through spectroscopic comparisons better understand the connectivity and structure of the amorphous ICP particles from which it is derived.
