Guest-specific function of a flexible undulating channel in a 7,7,8,8-tetracyano-p-quinodimethane dimer-based porous coordination polymer
We have designed and synthesized a flexible porous coordination polymer with highly selective capacity to separate benzene from cyclohexane. The undulating channel providing the suitable space for the benzene and the H-pi interaction between the host framework and the guest molecules result in this high selectivity.
