제목 Stretchable High-performance N-type Regio-Isomeric Polymers Based on Asymmetric Electron-Accepting Repeat Unit
초록 We have incorporated a newly formulated electron-accepting monomer unit(EA) into a series of n-type low-bandgap polymers with combination of cyclopentadithiophene (CDT) and indacenodithiophene (IDT) co-monomers. Controlling the regiregularity of the asymmetric electron-accepting monomer moiety has provided regio-isomeric polymer structures such as semi-regioregular (s-PCDT-EA and s-PIDT-EA) and regiorandom (r-PCDT-EA and r-PIDT-EA), respectively. We systematically performed comparative studies with respect to both the regio-chemistry control and CDT vs IDT repeat units in the polymers. All the polymers show excellent n-channel field-effect transistors with high electron mobility. Not only electron mobility, high intrinsical stretchability and organic phototransistor properties are also observed. The utilization of electron-accepting monomer can greatly facilitate the molecular design of next-generation n-type semiconducting polymers for stretchable and conformable electron devices.
