Abstract
Official abstract text for this publication.
This charge-transporting varnish, which includes a charge-transporting substance such as an aniline derivative or a thiophene derivative, an onium borate salt represented by, for example, the formula, and an organic solvent, allows a charge-transporting thin film having excellent charge-transporting abilities, flatness, and uniformity to be provided in a satisfactorily reproducible manner.
First claim
Opening claim text (preview).
1 . A charge-transporting varnish comprising a charge-transporting substance, an onium borate salt and an organic solvent, wherein the onium borate salt includes an onium borate salt consisting of an anion of formula (a1) and a counteraction (wherein R is an alkyl group of 1 to 10 carbon atoms, a fluoroalkyl group of 1 to 10 carbon atoms, an aralkyl group of 7 to 10 carbon atoms or a fluoroaralkyl group of 7 to 10 carbon atoms). 2 . The charge-transporting varnish of claim 1 , wherein the charge-transporting substance is at least one compound selected from the group consisting of aniline derivatives and thiophene derivatives. 3 . The charge-transporting varnish of claim 2 , wherein the charge-transporting substance is an aniline derivative. 4 . A charge-transporting thin film produced using the charge-transporting varnish of any one of claims 1 to 3 . 5 . An organic electroluminescent device comprising the charge-transporting thin film of claim 4 . 6 . A method for producing a charge-transporting thin film, comprising the steps of applying the charge-transporting varnish of any one of claims 1 to 3 onto a substrate, and evaporating off the solvent.
