Efficient detection and separation of pyridine from a pyridine/cyclohexane mixture using a clamparene-based organic porous cocrystal.

In this work, clamparene (CLP) and phthalimide (PDI) were employed to fabricate a stable porous cocrystal material driven by charge-transfer (CT) interactions. The obtained co-crystals exhibit selective and sensitive chromic responses to pyridine vapour, accompanied by fast adsorption kinetics and high uptake capacity.
