Special Issue Information

Dear Colleagues,

The development of semiconducting polymer nanoparticles (SPN) plays an important role in a wide range of electronic applications due to their potential use as electro-active materials. Conjugated polymers contain semiconducting properties, which provide great potential to replace inorganic semiconductors because they are lightweight and flexible, have tunable optoelectronic properties, and can be manufactured using low-cost processes, particularly in mass production.

Although organic semiconducting polymers show a greater advantage, more research is needed to improve their optical and electrical performances for biomedical and electronic applications. Thus, this Special Issue aims to assemble research articles and review papers that can represent the development and improvement in the design, synthesis, and characterization of high-performance SPN for photoacoustic imaging, photothermal therapy, chemical sensors, pressure-sensitive sensors, and related electronics. This Special Issue seeks contributions from academic and research institutions as well as industrial entities.

Extended π-conjugation with backbone-planarity-driven π-π stacking dominates charge transport in semiconducting polymers (SCPs). The roles of SCP film morphology and macromolecular conformation concerning the substrate in influencing charge transport and its impact on device performance have been a subject of extensive debate. Face-on SCPs promote out-of-plane charge transport primarily through π-π stacking, with conjugated polymeric chains assisting transport in connecting crystalline domains, whereas edge-on SCPs promote in-plane charge transport primarily through conjugation and π-π stacking. In this work, we fabricated three different types of devices, namely, organic field effect transistors, organic Schottky diodes, and organic bistable memristors, as representatives of planar and vertical devices. We demonstrate that a planar device, i.e., an organic field effect transistor, performs well in an edge-on conformation exhibiting a field-effect mobility of 0.12 cm2V−1s−1 and on/off ratio >104, whereas vertical devices, i.e., organic Schottky diodes and organic memristors, perform well in a face-on conformation, exhibiting exceptionally high on/off ratios of ~107 and 106, respectively.
