제목 Fabrication of Highly Crystallized Multi-Pathways Poly(3-hexylthiophene) (P3HT) Thin Films
초록 Conjugated polymers (CPs) have been considered promising candidates for next-generation organic electronics and optoelectronics. In these applications, the controlling of crystallinity and molecular chain packing in CP films is a key factor for the optimization of device performances. Here, we suggest a new one-pot strategy to create a high quality and large area organic semiconducting thin film using Poly(3-hexylthiophene) (P3HT). We successfully obtained highly crystallized multi-pathways P3HT thin films by dropping a P3HT solution onto a surface of the water. Dropped P3HT solution is spread on a water substrate. Then, the organic solvent can be evaporated with the simultaneous inducement of self-assembly of P3HT and the formation of thin films without any additional processing and additive. The fabricated thin film can be easily transferred to other target substrates for fabrication organic field-effect transistors (OFET) devices with outstanding charge carrier mobility.
