The shape-memory effect in crystalline porous materials is poorly understood. An international team of researchers (Ireland, Japan, University of Southern Florida) reports the porous coordination network that exhibits a sorbate-induced shape-memory effect in which multiple sorbates, N2, CO2 and CO promote the effect. It exhibits three distinct phases: the as-synthesized α phase; a denser-activated β phase; and a shape-memory Îł phase. Analysis of the structural information of the three phases helped them to understand structure-function relationships and propose crystal engineering principles for the design of more examples of shape-memory porous materials… read more.
