Abstract Porous organic polymers POPs incorporating macrocyclic units have been investigated in recent years in an effort to transfer macrocycles' intrinsic host—guest properties onto the porous networks to achieve complex separations. In this regard, highly interesting building blocks are presented by the family of cyclotetrabenzoin macrocycles with rigid, well-defined, electron-deficient cavities.
This macrocycle shows high affinity towards linear guest molecules such as carbon dioxide, thus offering an ideal building block for the synthesis of CO 2 -philic POPs. Notably, following the condensation reaction, the macrocycle favors three-dimensional 3D growth rather than a two-dimensional one while retaining the cavity. The Author s.
