Reflecting on synthetic pinnacles: Whereas the parent hydrocarbon is not readily accessible, several examples of BN substituted-dibenzo[a,o]picenes can be prepared in two steps from known starting materials. These non-linear heptacene analogues are water-stable materials. Their preparation utilizes a potentially general method for preparing extended BN analogues of difficult-to-synthesize polycyclic aromatic hydrocarbon frameworks.
虽然母体碳氢化合物不易获得，但可以从已知起始原料通过两步法制备几个 BN 取代的二苯并[a,o]菲。这些非线性并五苯类似物是水稳定的材料。它们的制备利用了一种潜在的通用方法，用于制备难以合成的多环芳烃骨架的 BN 类似物。
