Conjugated microporous polymers (CMPs) are a unique class of polymers that consist of an extended π-conjugated backbone and reactive side groups. Owing to the non-planar configuration of the monomer, these polymers form a solid 3D crosslinked framework that facilitates charge transport in the polymers. Herein, we report the synthesis of CMP films …
