Application

PQT-12 can be employed as the semiconductor material in organic field-effect transistors(OFETs). Its high charge carrier mobility, good film-forming properties, and stability make it useful for the channel layer, enabling efficient electronic device performance. The conjugated polymer structure and charge storage capability of PQT-12 make it potentially useful for energy storage applications such as super capacitors and batteries.
PQT-12 exhibits strong absorption in the visible and near-infrared regions of the spectrum. This property enables effective utilization of a broad range of solar radiation, enhancing the light-harvesting capability and efficiency of OPV devices. PQT-12 can serve as the donor material in the active layer of OPV devices. PQT-12′s unique properties and charge transport characteristics contribute to the development of low voltage and low-power OFET devices. Its high charge carrier mobility allows for better device performance with lower operational voltages.

High Crystalline, Solution-Processable Organic Field-Effect Transistors

Dr. Chan and researchers highlight flexible transistors are the building blocks of next-generation soft electronics. Among all the reported material systems that can be fabricated by researchers, such as circuits, biosensors, stretchable displays, and others,1–5 small molecular weight organic semiconductors are among the most promising candidates for flexible transistor applications. For these small molecular weight organic semiconductors, the semiconductor forming the conductive channel dominates the device performance.
