英文摘要： Due to the broad and attractive application prospect, polymer semiconductor and their field-effect transistors (FETs) have attracted tremendous attention by domestic and foreign academic institutions and enterprises. The related research has become one of focuses in the field of organic electronics in recent years. Polymer semiconductor materials are the core of the FET devices; their properties determine the performance of the electronic devices. Therefore, the design and synthesis of high performance polymer semiconductor materials are the basis and premise of wide application of such FET devices. Nowadays, the electron mobility and their devices stability of n-type and ambipolar polymer semiconductors still fail to meet the requirement of industrial application. In the proposal, the applicant aims at these key issues and proposes to develop a series of new, planar indolin-2-one-based monomers and polymers, as well as adjusts their energy levels of HOMOs and LUMOs and energy gaps etc., by the introduction of different aromatic building blocks, heteroatoms and other substituent groups, so as to achieve high performance n-type and ambipolar polymer semiconductor materials. Moreover, the applicant would seek to further clarify the structure-property relationship, by the selection and modification dielectric layer of FET devices, the morphology optimization of polymer films, the comparison of device structures and field-effect properties etc. The research project has important scientific significance.
