title: Synthesis, physical properties, and field-effect mobility of isomerically pure syn-/anti-anthradithiophene derivatives.
abstract: 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.
