چکیده انگلیسی
A wide variety of Ï-conjugated polymers have been synthesized by using organometallic polycondensations. For instance, Ni(0) complex-promoted dehalogenative polycondensation of dihaloaromatic compounds, X-Ar-X, affords poly(arylene)s, -(Ar)n-. Pd-catalyzed polycondensation gives alternating copolymers, -(Ar-Arâ²)n-, and poly(arylene-ethynylene)s, -(Ar-CC-Arâ²-CC)n-. These polymers show distinguishing optical and electrochemical properties and functionalities. Their well-characterized linear structures lead to molecular assembly and packing of the polymer molecules in solutions and in the solid state. In this article, we describe the synthesis of Ï-conjugated polymers by the organometallic polycondensations, chemical properties of the synthesized polymers, and applications of the polymers for electronic and optical devices.
