Abstract

Abstract : The aggregation of conjugated polymers is found to have a significant influence on the surface organization of deposited films. Difluorobenzothiadiazole‐based polymers show a strong pre‐aggregation in solution, but the addition of 1, 2, 4‐trichlorobenzene efficiently reduces such aggregates, leading to the transition of the surface organization from edge‐ to face‐on orientation in deposited films.
