This HOT Communication from Huaqiang Zeng and co-workers describes a 1D helical channel, composed of short foldamers with sticky ends that self-assemble in the solid state, that acts as a CH2Cl2 channel. What is interesting is that the Cl⋯Cl intermolecular distances within the channel are extraordinarily short. Zeng et al. perform computational modelling and calculate that this unusually short distance destabilises the host–guest complex by 14.94 kcal mol-1.
This will be free to access for the next 4 weeks so why not have a look at modelling details.
