AI Technical Summary
Existing organic semiconductor materials face challenges with doping due to the volatility, high absorption coefficient, unstable evaporation rate, and low thermostability of commonly used p-dopants, which also come with high production costs.
The use of cerium (IV) complexes as p-dopants and electron transport materials in organic electronic components, which exhibit better conductivity, improved thermostability, and higher doping efficiency, while being cost-effective and suitable for both vacuum coating and solvent-based processing.
Cerium (IV) complexes demonstrate enhanced conductivity and thermostability in doped layers, leading to improved performance and reduced parasitic absorption in organic electronic components, with the added benefit of lower production costs.
