The o‐carborane‐based π‐conjugated compound, benzocarborano‐ [2,1‐b:3,4‐b′]dithiophene was synthesized. Its crystal structure revealed high coplanarity for the two thiophene rings of the 2,2′‐bithiophene skeleton, which is fixed in the cisoid structure by the o‐carborane unit. Theoretical calculations indicated non‐aromaticity for its center C6 ring moiety as well as decreased HOMO and LUMO levels
所述Ô -carborane基于π共轭化合物,benzocarborano- [2,1- b:3,4- b ']二噻吩的合成。其晶体结构揭示高的共面的2,2'-联噻吩骨架,其被固定在所述的两个噻吩环cisoid由结构Ó -carborane单元。理论计算表明其中心C 6环部分具有非芳香性,并且HOMO和LUMO含量降低。所述Ô -carborane部分提供通过电感作用的吸电子性质的2,2'-联噻吩单元。
