由液晶相制备的多晶薄膜在毫米和纳米尺度上都相当均匀。用两种模型液晶材料--二烷化三硫吩衍生物和苯并硫苯并噻吩衍生物制备了均匀的多晶薄膜，其FET迁移率分别为0.1cm2V(-1)和3.0cm2V(-1)S(-1)。这种均匀的薄膜不是通过后热退火获得的。
Polycrystalline thin films fabricated from a liquid crystalline phase are quite uniform both on the millimeter and nanometer scale. The uniform polycrystalline thin films are established by two model liquid crystalline materials, dialkylated terthiophene and benzothienobenzothiophene derivatives, and show high FET mobility, 0.1 and 3.0 cm(2) V(-1) s(-1), respectively. Such uniform films are not obtained by post thermal annealing.
