Kanazawa University Research: Vapor Drives a Liquid-solid Transition in a Molecular System

- Tomoki Ogoshi from Kanazawa University in Japan and colleagues studied pillar[n]arene molecules pillar-shaped molecules that were first reported by their research group to which functional groups can be added to modify their physical properties.
- The liquid solidifies when exposed to a guest vapor, whose molecules replace the n-hexyl substituents in the cavities of the pillar-shaped molecules.
- The result is that, on a timescale of a few seconds, the system solidifies and the transparent liquid changes to a turbid solid.
- "Because of the vapor selectivity, we postulate the vapor-induced state change can be applied for new vapour detection systems," comment the authors.
