Abstract

Conjugate polymers (CPs), especially the alternating CPs, have attracted much attention since they have applications in many fields, including energy, information, and biology. Currently, the synthesis of alternating CPs mainly depends on the transition metal-catalyzed cross coupling reactions. Due to the homocoupling side reactions, there are intrinsic structural defects in the backbones of the CPs, resulting in detrimental electronic properties, large batch-to-batch variation, and unclear structure-property relationship. Thus, it is important to develop new methods for precise and scalable synthesis of CPs.
In this talk, we will report several novel synthetic methods for precision synthesis of CPs including an original C-S bond activation based polymerization (CASP) method. We will discuss the catalytic systems, the structural defects and the catalytic mechanisms. Also, we will present the challenges and prospects of this field.
