Enthalpically and Entropically Favorable Self‐Assembly: Synthesis of C _{4 h} ‐Symmetric Tetraazatetrathia[8]circulenes by Regioselective Introduction of Pyridine Rings

Self‐assembly of π‐conjugated molecules in solution generally occurs owing to either an enthalpic or an entropic gain; however, designing π‐conjugated systems that simultaneously exhibit enthalpically and entropically favorable self‐assembly behavior is challenging. Herein, the self‐assembly behavior of tetraazatetrathia[8]circulenes is disclosed, which is driven by both enthalpy and entropy. Single‐crystal X‐ray diffraction analysis...
