不同的B（硼）-π-N（氮）嵌入模式是否导致相同大环分子骨架的不同（光）电子性质？为了解决这一问题，我们合成了一系列交替间位对位连接的B-π-N嵌入环番1-3，并表征为一类新的双极性π-共轭B-π-N大环化合物。对开头问题的回答是肯定的。结果表明，大环化合物在氧化态存在分子内电荷转移，并具有与嵌入模式相一致的物理化学性质，表明通过引入多个B-π-N基团可以调节化合物的电子结构.更多信息可参见Akihiro Ito，Hiroyuki Fueno et al.在2018年第7期第754页的通信（DOI：10.1002/asia. 201701717）。
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.
