Front Cover: Diazadibora[1.1.1.1]m,p,m,p‐cyclophanes: Ambipolar Conjugated Macrocycles with Different B–π–N Embedded Patterns (Chem. Asian J. 7/2018)

Are different B (boron)–π–N (nitrogen) embedded patterns resulting in different (opto)electronic properties for the same macrocyclic molecular backbone? To address this question, a series of B–π–N embedded alternate‐meta‐para‐linked cyclophanes 1–3 have been prepared and characterized as a new class of ambipolar π‐conjugated B–π–N macrocycles. The answer to the opening question was found to be yes. The results revealed an intramolecular charge transfer in the oxidized states of the macrocycles and intriguing photophysical properties in accordance with the embedded patterns, suggesting that the electronic structures are tunable by introducing multiple B–π–N moieties.
