Special Issue Information

Dear Colleagues,

Conjugated polymers are organic macromolecules with a backbone chain of alternating double- and single- bonds. Delocalised π-electrons from neighbouring overlapping p-orbitals enable the traditional ‘plastics’ to achieve metallic electrical conductivity and lead to interesting and useful optical and electronic properties. These electronic materials have attracted the joint attention of synthetic chemists, material physicists, and device engineers. Importantly, conjugated polymers have demonstrated diverse applications in flexible organic photovoltaics, transistors, polymer light-emitting diodes, bioelectronics (with mixed ionic and electronic conductivity), and more. 

This Special Issue aims to present the recent advancements in the field of functional conjugated polymers. Topics of interest include, but are not limited to:

  • Design and synthetic strategies for conjugated polymers;
  • Novel functionalization and post-polymerization modifications;
  • Structure-property relationships in conjugated polymers;
  • Applications of conductive polymers, such as OPVs, OFETs, and OLED, etc.;
  • Mixed ionic and electronic conduction in conjugated polymers and bioelectronics;
  • Conjugated polymer composites;
  • Sustainable conjugated polymers.

I sincerely invite you to submit original research articles, reviews, and short communications to this Special Issue. Please contact the editorial team if you have any enquiries related to your submission.

Kind regards,
Dr. Qiao He
Guest Editor

Conjugated polymers have gained considerable interest due to their unique structures and promising applications in areas such as optoelectronics, photovoltaics, and flexible electronics. This review focuses on the structure–property relationship, glass transition, and crystallization behaviors of conjugated polymers. Understanding the relationship between the molecular structure of conjugated polymers and their properties is essential for optimizing their performance. The glass transition temperature (Tg) plays a key role in determining the processability and application of conjugated polymers. We discuss the mechanisms underlying the glass transition phenomenon and explore how side-chain interaction affects Tg. The crystallization behavior of conjugated polymers significantly impacts their mechanical and electrical properties. We investigate the nucleation and growth processes, as well as the factors that influence the crystallization process. The development of the three generations of conjugated polymers in controlling the crystalline structure and enhancing polymer ordering is also discussed. This review highlights advanced characterization techniques such as X-ray diffraction, atomic force microscopy, and thermal analysis, which provide insights into molecular ordering and polymer–crystal interfaces. This review provides an insight of the structure–property relationship, glass transition, and crystallization behaviors of conjugated polymers. It serves as a foundation for further research and development of conjugated polymer-based materials with enhanced properties and performance. Full article
