Switching molecular recognition selectivities by temperature in a diffusion-regulatory porous material.

ABSTRACT: Over the long history of evolution, nature has developed a variety of biological systems with switchable recognition functions, such as the ion transmissibility of biological membranes, which can switch their ion selectivities in response to diverse stimuli. However, developing a method in an artificial host-guest system for switchable recognition of specific guests upon the change of external stimuli is a fundamental challenge in chemistry because the order in the host-guest affinity of a given system hardly varies along with environmental conditions. Herein, we report temperature-responsive recognition of two similar gaseous guests, CO₂ and C₂H₂, with selectivities switched by temperature change by a diffusion-regulatory mechanism, which is realized by a
