Combining the optoelectronic characteristics of the conjugated polymers and the self-assembling behavior of the block polymers,all-conjugated block copolymers have been developed as a new class of optoelectronic functional materials with unique self-assembling behavior in recent years. Researching on the relationship among its assembling structure,the mechanism of self-assembly and the photophysical properties has significant impacts on the manipulating nanoscale morphology patterns of conjugated polymers and the development of organic photovoltaic devices. This paper reviews the development of the synthesis process of all conjugated block copolymers including conjugated polyelectrolytes. Their unique behavior of self-assembly in solution and thin-film state is discussed. Finally,the application of conjugated polymers in optoelectronic devices is introduced,and its future research and development are prospected.
