N-doping of organic semiconductors catalysed by organometallic complexes.

ABSTRACT: Molecular doping is essential for optimizing carrier concentration, charge mobility, and energy levels of organic semiconductors (OSCs), thereby enhancing device performance. However, efficient n(electron)-type doping remains challenging, as conventional techniques often fail to achieve high doping efficiency with minimal counterion-induced disorder under mild conditions. Here, we present a catalysed n-doping strategy for OSCs using air-stable, cost-effective, and commercially available soluble organometallic complexes, such as Pt(COD)Cl₂, which enable rapid n-dopant activation with just 10 s of annealing at 120 ^oC. This approach demonstrates excellent generality across diverse OSCs, dopants and catalysts, achieving electrical conductivities exceeding 230 S cm^-1<
