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.
