通过六烷氧基苯并菲衍生物的逐步锂化反应和杂原子试剂的处理，合成了由两个亚苯基二噻吩单元和14族桥原子组成的螺型杂环氧化物。通过单晶X-射线衍射分析确定了含有两个正交π骨架的螺二杂螺螺环烯的分子结构。逐步可逆的双电子氧化过程揭示了正交π-骨架在氧化态下通过螺共轭相互作用。
Spiro-type heterasumanenes composed of two triphenylenodithiophene units and group 14 bridging atoms were synthesized by stepwise lithiations of hexaalkoxytriphenylene derivatives and treatment with heteroatom reagents. The molecular structures of the spirobiheterasumanenes, which contain orthogonal two π-frameworks, were determined by single-crystal X-ray diffraction analyses. The stepwise and reversible two-electron oxidation process revealed that the orthogonal π-frameworks interact with each other through spiro-conjugation in their oxidized state.
