摘要：
The bridging of distyryl-bithiophene leads to a kite shape of the conjugated system. This twist is not like twistacenes or twist deformation in alpha-oligothiophenes but a curvature such as in bowl shaped systems. Initially perceived to be undesirable, this new semiconductor in OTFT devices provides excellent performances in air, mu = 0.1 cm(2)/V.s, I-on/I-off > 10(6), S < 4 V/decade, higher by a factor of 5 to the parent unbridged coplanar analogue.
