Applications brief: Polypeptide-assisted organization of pi-conjugated polymers into responsive, soft 3D networks

Key points

  • Nanoscale IR spectroscopy confirmed that alpha-helical secondary formation of PBLG was unaffected by the presence of pi-conjugated polymer chains
  • PBLG self-assembly thermoreversible gels with long-range ordered structures provides a foundation for the design of biocompatible materials
  • Results offer new opportunities to harness the propensity of polypeptide assembly into interconnected fibrillary structures to control the organization of semiconducting polymers, and explores hybrid gels as active materials in bioelectronics
