Spring-like porous crystals could enable chemically responsive microscale materials

Crystals are usually imagined as rigid objects with flat faces and straight edges. A research team led by the University of Osaka has recently created a porous crystal that grows into a spring-like helix. The team also found that the crystal can change shape as solvent molecules move in and out of its internal spaces. Their findings are published in Angewandte Chemie International Edition.
