Synthesis of pi-conjugated materials and their application in field-effect transistors

Abstract

pi-Conjugated materials have attracted much attention as promising candidates for the development and production of the next generation of electronics, that is, organic electronics. Conceptually, organic electronics are quite different from conventional inorganic solid state electronics because the structural versatility of organic semiconductors allows for the incorporation of functionality by molecular design. This versatility leads to a new era in the design of electronic devices. To date, the great number of pi-conjugated semiconducting molecules that have either been discovered or synthesized generate an exciting library of π-conjugated materials for use in organic electronics. However, some key challenges for further advancement remain: the low mobility and stability of organic semiconductors, the lack of knowledge regarding structureproperty relationships for understanding the fundamental chemical aspects behind the structural design, and realization of desired properties. Organic/polymer field-effect transistors (O/PFETs) are of great interest for practical applications in active-matrix displays, radiofrequency identification tags, biosensors, and integrated circuits owing to their advantages of low cost, light weight, and mechanical flexibility. In this presentation, I will report design and synthesis of a series of pi-conjugated materials, a few results on fabrication and investigation of O/PFETs,[1–10] particularly on device interfaces and performances.
