Planar backbone, locked conformation, and low lowest unoccupied molecular orbital level provide polymer F4 BDOPV-2T with ultrahigh electron mobilities of up to 14.9 cm(2) V(-1) s(-1) and good air stability. It is found that the nonlinear transfer curves can be tuned to near-ideal ones by changing fabrication conditions, indicating that film morphology largely contributes to the nonlinear transfer curves in high-mobility conjugated polymers.
平面主链、锁定构象和低最低未占据分子轨道能级赋予聚合物 F4BDOPV-2T 超高的电子迁移率，高达 14.9cm^(2)V^(-1)s^(-1)，并且具有良好的空气稳定性。研究发现，通过改变制备条件可以将非线性传输曲线调至近理想状态，这表明在高迁移率共轭聚合物中，薄膜形态对非线性传输曲线有很大的影响。
