six carbon atoms show nanofiber morphology. The polymer nanofibers were stacked on a substrate electrode. The fluorescence of the polymer nanofiber film was tunable with application of voltage, with good repeatability. The X‐ray diffraction pattern of the fibers showed the structural order. The polymer nanofibers thus prepared showed an electrochemically driven change in polarized photoluminescence.
一系列N的电化学聚合进行乙腈中的2,7,7-二(2-噻吩基)烷基烷基咔唑制得具有荧光的共轭聚合物。扫描电子和原子力显微镜检查显示,聚合物膜的表面形态显着取决于聚合物的烷基链长度。特别地,带有己基的均聚物和具有六个碳原子的平均烷基链长的共聚物显示出纳米纤维形态。聚合物纳米纤维堆叠在基板电极上。施加电压可调节聚合物纳米纤维膜的荧光,具有良好的重复性。纤维的X射线衍射图显示了结构顺序。如此制备的聚合物纳米纤维在偏振光致发光中显示出电化学驱动的变化。
