[6](1,4)Naphthalenophane (1a), [6](1,4)anthracenophane (2a), and their peri-substituted derivatives 1b, 1c, and 2b were synthesized from 8-bromo[6]paracyclophane (4) by a benzoannelation method. The 1H NMR spectral properties of 1b, 1c, and 2b as well as the X-ray crystallographic structure analysis of 1b indicate that their bridged aromatic rings are more distorted than those of the corresponding
[6](1,4)萘酚 (1a)、[6](1,4)蒽酚 (2a) 及其周边取代衍生物 1b、1c 和 2b 由 8-溴[6] 对环烷 (4 ) 通过苯甲醚化方法。1b、1c 和 2b 的 1H NMR 光谱性质以及 1b 的 X 射线晶体结构分析表明,它们的桥接芳环比相应的母体系统 1a 和 2a 更扭曲。1b 和 2b 的热可逆光化学异构化很容易发生,得到相应的杜瓦价异构体,10b 和 11b。
