Organic semiconductor OLED Alq3 single crystal Growth Ionic liquids
The organic semiconductor is promising material for flexible electronics due to many advantages such as simple manufacturing process, inexpensive, and flexibility. The high purity single crystal of the organic semiconductor, however, is not easily obtained and thus degradation of electrical property is a big hurdle for organic electronics applications. We have investigated the growth mechanism of Alq3 single-crystal using a [C12mim][TFSI] ionic liquid as a solvent. Isothermal heat-treatment has been carried out at 100℃ for 1h, 3h, 24h, and 120h with 9 mol% composition. We can make high quality single crystal of Alq3 via just one time process using ionic liquid. The shape of Alq3 single-crystal changes from hollow structure to filled hexagonal-rod shape. Now we are trying to measure the electrical properties of the Alq3 single crystal. Our research could be promising process to improve electrical properties of organic semiconductor such as Organic Light Emitting Diode (OLED), Organic Thin Film Transistor (OTFT), and Organic Solar Cell.
