“…Interestingly, contrary to the precursor polymer, cLP 2 was found to be readily doped with F 4 TCNQ. It was recently reported that the extended π‐conjugation and coplanar nature of the ladder‐type molecules are crucial to facilitate charge transfer interactions with F 4 TCNQ [15] …”

“…It was recently reported that the extended π-conjugation and coplanar nature of the ladder-type molecules are crucial to facilitate charge transfer interactions with F 4 TCNQ. [15] Ring-closing olefin metathesis was also utilized for the synthesis of a porous ladder polymer network (PLAN), which led to entropically favorable gas adsorption. [16] Despite the successful examples of cLP synthesis via RCM, using vinyl functional which are rather challenging to introduce and have moderate functional group tolerance during the reactions, might confine the synthetic approach utilizing RCM.…”

Conjugated ladder polymers (cLPs) are macromolecules consisting of fully fused aromatic backbones, which have emerged as an intriguing research area due to their unique electronic and optoelectronic properties. They possess a highly ordered, ladder‐like structure, which leads to improved charge transport properties and enhanced stability compared to conventional conjugated polymers. The synthesis of cLPs involves two main strategies: single‐step ladderization and stepwise ladderization. However, due to the extremely low solubility of the desired cLPs and the limited synthetic methods for preparing defect‐free cLPs, the field of solution‐based synthesis and processing of cLPs encountered synthetic and processing challenges. This review provides an overview of recent achievements in the synthesis of conjugated ladder polymers, emphasizing the challenges and potential in this fascinating field of research.
