â╬-Conjugated polymers are electrically conductive and light-emitting. They are film-forming, and their films possess flexibility and thermostability. They are attracting much attention as future materials for electronic and optical devices. Variousâ╬-conjugated conductive polymers have been synthesized via organometallic polycondensations mediated by organotransition metal complexes, and their applications to thin-film-transistors (TFT), organic-light-emitting diodes (OLED), photovoltaic cells, etc. are actively researched.
In this chapter, we describe synthetic methods of â╬-conjugated conductive polymers using organometallic polycondensations. For example, Ni(0) complex-promoted dehalogenative polycondensation of dihaloaromatic compounds X-Ar-X affords poly(arylene)s , and Pd-catalyzed polycondensation gives poly(arylene-ethynylene)s, etc. Applications of conducting polymers to organic-thin-film-transistors and organic-light-emitting diodes are also described.
