合成了一系列含七元内杂环联苯化合物(6,6'位不同取代的2,10-二溴-6H-双 苯[d,f][1,3]双氧杂草和2,10--'醛- 6H-双苯[d,f][1,3]双氧杂草),通过 元素分析、核磁共振氢谱、紫外可见吸收光谱对它们的结构进行了表征,用X-ray 单晶衍射测定了部分化合物的晶体结构.结果表明这类化合物具有相同的刚性扭曲 构型,其二个苯环扭曲角的大小受6,6,取代基团的影响可以发生8°(35°~43. 1°)的变化。

A series of bridged biphenyls containing dioxygen group in the bridge were synthesized. The structures of the compounds were characterized by elemental analysis,~1H NMR, UV-vis spectra and X-ray diffraction analysis. These compounds possess the same rigid-twisted conformation, and the twisted angle between two benzene rings can be influenced by 6,6'-substituent groups, which may be changed up to 8° (35° ~ 43.1°).
