Map ESR Project 5


  • Synthesis of p-type conjugated polymers, esp. polythiophenes, with different types of polar side chains based on oligoethylene glycol, to achieve a low ionization potential and good solubility
  • Synthesis of polar conjugated polymers with different side chain lengths and branching to optimize solid state packing
  • Synthesis of copolymers of polar polythiophenes with non-conjugated blocks to adjust rheological and mechanical properties
  • Upscaling of the synthesis of the two most promising materials to the 10-gram scale.

Expected results

  • New polythiophenes with optimal side chain type that can be processed together with p-dopants from the same solution and show optimal thermoelectric performance
  • Synthesis of the two most promising materials upscaled to the 10-gram scale, for delivery to WP2 and 4.

Skills acquired

  • In-depth understanding of synthesis and characterization of conjugated polymers, including upscaling
  • Basic knowledge of TE characterization techniques
