摘要
Transfer printing of small-molecular organic semiconductors often faces challenges due to surface adhesion mismatch.Here,we developed a sacrificing-layer-assisted transfer printing technique for the deposition of smallmolecular thin films.High-boiling-point ethylene glycol(EG)was doped in aqueous solution poly(3,4-ethylenedioxythiophene)polystyrene sulfonate(PEDOT:PSS)as the sacrificing layer to manipulate residual water in film,which allowed chlorobenzene solution to spontaneously spread and form uniform film.
