| 英文摘要 | the effect of thermal treatment on the transition of molecular packing and orientation of the semiconducting poly(2,5-dihexyloxy-p-phenylene) (ppp) film is probed by the combination of in situ 2d grazing incidence x-ray diffraction (2d gixd) and selected area electron diffraction (saed). the structure analysis indicates that ppp crystallizes in an orthorhombic unit cell with a = 21.20 angstrom, b = 3.78 angstrom, and c = 4.24 angstrom. a variation of the annealing temperature from 80 degrees c to 100 degrees c demonstrates that the worm-like morphology in the pristine film melts and develops into nanowires. furthermore, the molecular orientation transforms from face-on to edge-on via thermal annealing. remarkably, a previously unknown metastable state of slope edge-on with a tilt angle of 51.1 degrees is observed. this orientation change arises from the heterogeneous nucleation and growth of edge-on ppp crystal during crystallization from the melt. |
