Conjugated polymers (CPs) have received attention due to broad applications for biosensor, organic field effect transistor (OFET), light-emitting diodes, and solar cells. Among various CPs, poly(3-hexylthiophene) (P3HT) has been widely studied due to solution-processability and relatively high carrier mobility. The carrier mobility can be determined by the crystallinity degree of CPs besides the molecular structure considering bandgap. However, it remains to be studied whether a solvent can be selected to increase crystallinity and transfer it to the film without crystals decomposition, and whether there is any further consideration during the film process. Herein, we studied the simple process to produce 1D P3HT nanostructures with high crystallinity by regulating the mixing rate of good and orthogonal solvents. Also, we investigated the effect of orthogonal solvents with different solubility parameters on the crystalline properties of P3HT thin film and mobility in its transistor. |
