Abstract

Within the framework of Huckel molecular orbital theory, it has been found that similar as cyclacenes monoazacyclacenes exhibit some cryptoannulenic behavior, and their angle of total pi-electron energies fluctuates within the series, depending on the size and type of the peripheral circuit (4m or 4m + 2 type). However, this effect in monoazacyclacenes is less pronounced as compared to cyclacenes.
