ABSTRACT A rigid aromatic macrocycle was synthesized selectively by a traditional one-step [1+1] cyclization between bisphenol-A and1,3-bis(4-fluorobenzoyl)benzene under a pseudo-high dilution condition.A single-crystal X-ray analysis of the resulting macrocycle shows the molecule to be slightly strained with a free pathway through the ring center. The rigid macrocyclic structure of the dimer is stable despite of its small ring size. The macrocycles stack along the crystallographic b direction to create continuous channels. Adjacent channels are linked by π-π stacking and a Van der Waals intermolecular action.
