The synthesis of isomerically pure syn-anthradithiophene derivatives (syn-ADTs) is described. X-ray crystallography is used to compare the solid-state arrangement of syn-ADT derivatives 2a,b to the analogous mixture of syn- and anti-ADTs. Single-crystal OFETs based on isomerically pure syn-ADTs 2a,b display device performance comparable to those based on a mixture of ADT isomers syn/anti-2a,b with mobilities as high as 1 cm(2)/(V s).
本文描述了对映纯 syn-蒽并噻吩衍生物（syn-ADTs）的合成。通过 X 射线晶体学比较了 syn-ADT 衍生物 2a,b 的固态排列与类似的 syn-和 anti-ADT 混合物。基于对映纯 syn-ADTs 2a,b 的单晶 OFET 显示出与基于 syn/anti-2a,b ADT 异构体混合物的器件性能相当，迁移率高达 1 cm(2)/(V s)。
