Alignment Behaviors on ITO Glass and Electrical Properties of Triphenylene Compound
The alignment of 2, 3, 6, 7, 10, 11-hexapentaloxy triphenylene (HAT5) on ITO glasses was investigated by polarizing optical microscopy, differential scanning calorimeter, X-ray diffraction and scan scanning electron microscope in this study. The results showed that the alignment of 2, 3, 6, 7, 10, 11-hexapentaloxy triphenylene can be fixed at room temperature by heating the sample to the isotropic temperature and annealing at 100°C overnight and then cooling slowly back to room temperature; the ordered arrangements of the micro structures are disconnected. The disconnection of the microstructure and the size of columnar assemblies can also be confirmed from the SEM observations.
