It is desirable to design and synthesize a bipolar polymer that possesses both a hole-injecting/transporting segment and an electron-affinitive segment to balance the rates of injection of electrons and holes, and to enhance the charge-injecting/transporting ability. As such, the synthesis and primary characterization of four novel alternating copolymers containing π-deficient and π-excessive units in a conjugated main chain for pursuing efficient single-layer polymer light-emitting diodes (LEDs) are presented. It is found that the resulting copolymers are thermally stable above 370°C.
