Highly conductive organic semiconductors were achieved using solution-processed fulleropyrrolidinium iodide (FPI) and FPI-doped PCBM. This n-doping method utilizes anion-induced electron transfer for enhanced electrical conductivity in fullerene materials.

Area of Science:

  • Materials Science
  • Organic Electronics
  • Solid-State Chemistry

Background:

  • Organic semiconductors are crucial for flexible electronics.
  • Achieving high conductivity in n-type organic semiconductors remains a challenge.
  • Solution-processible materials offer cost-effective manufacturing advantages.

Purpose of the Study:

  • To demonstrate a novel n-doping strategy for solution-processible organic semiconductors.
  • To achieve highly conductive fullerene-based materials.
  • To elucidate the mechanism of anion-induced electron transfer in solid-state fullerene systems.

Main Methods:

  • Solution-processing of fulleropyrrolidinium iodide (FPI).
  • Incorporation of FPI as an n-dopant for PCBM (phenyl-C61-butyric acid methyl ester).
