Fig. 1: The working principle of guest-adaptive molecular sensing for dynaCOFs.
From: Guest-adaptive molecular sensing in a dynamic 3D covalent organic framework

a Traditional molecular recognition of the sizes and shapes of guest molecules via the self-adaptivity of supramolecular macrocycles and cages for molecular sensing in liquids (solutions). b Dynamic and functional confinement spaces for the docking of guest molecules and the adaptive inclusion of more guests to output molecular-specific fluorescent responses varied in intensity and colours for multiplex molecular sensing of gas/vapours.
