Full‐Range Tunability of Electron and Hole Carrier Mobilities and Density Ratios via Incorporation of Highly Electron‐Deficient Moieties in Poly(phenylene vinylene) Side Chains
Source abstract
Abstract
The incorporation of a triazole moiety in poly(phenylene vinylene) (see Figure) allows tuning of the ratio of electron flux to hole flux over a broad range. Originally hole‐dominated transport can be turned to electron‐dominated transport. At proper triazole content, electron and hole fluxes are balanced, and the efficiency and brightness of a device with a high work function Al cathode can be improved to the level of low work function Ca.
