Abstract (en)

[origin: GB2551585A] Solvent blends for the preparation of semiconductor formulations with improved stability for ink jetting applications, the solvent blends comprising an alkyl benzoate or aryl benzoate; a first aromatic hydrocarbon. which is a dialkyl- or trialkylsubstituted aromatic hydrocarbon; and a second aromatic hydrocarbon different from the first aromatic hydrocarbon. An example blend is benzyl benzoate, trimethyl benzene and 1-methylnaphthalene or diphenylmethane. In addition, methods of manufacturing organic electronic devices with high efficiency and high-quality photoactive layers and films by using said formulations are disclosed.
