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.
