Isomerically pure syn-/anti-isomers of 2,8-dimethylanthradithiophene (DMADT) were synthesized in five steps and characterized using thermogravimetry, X-ray single crystal analysis, UV-vis absorption, and electrochemical measurements. The physical properties in solution were slightly different for each isomer, whereby the more obvious differences were observed in the solid state. A field-effect transistor using the anti-isomer showed a much higher performance than that using the syn-isomer.
通过五步反应，我们合成了 2,8-二甲基蒽并[2,3-b]噻吩（DMADT）的对映异构体纯的顺/反异构体，并通过热重分析、X 射线单晶分析、紫外可见吸收和电化学测量对其进行了表征。每种异构体在溶液中的物理性质略有不同，在固态中观察到的差异更为明显。使用反式异构体的场效应晶体管的性能明显高于使用顺式异构体的场效应晶体管。
