A Fast and Convenient Synthesis of Heterocycle-Based Polymers via Infrared Irradiation-Assisted Direct C–H Bond Arylation Polymerization in Quasi-Solvent-Free Conditions

used as reference (5.9%). Our results confirm that the experimental advantages of DArP reactions combined with the use of IR irradiation and the quasi-solvent-free conditions represent a straightforward and sustainable route to heterocycle-based polymers for organic solar cells.
