CHARGE-TRANSPORTING VARNISH |
摘要 |
This charge-transporting varnish includes: a fluorine-containing charge-transporting substance; a non-fluorine-containing charge-transporting substance; a dopant substance comprising a heteropoly acid; and an organic solvent. The fluorine-containing charge-transporting substance is a polymer which has a weight average molecular weight of 500-200,000, and which is obtained by condensing: at least one compound selected from triarylamine compounds and tetraarylbenzidine compounds; a tetraarylbenzidine compound having at least one aryl group substituted with an alkoxy group which may include ether bonds; a fluorine-containing aryl aldehyde compound; and a fluorene derivative having a carbonyl group. The non-fluorine-containing charge-transporting substance is an oligoaniline compound. The charge-transporting varnish provides a thin film with which an organic electroluminescent element exhibiting excellent luminance characteristics can be achieved, even in cases when employed as a single layer in a state of being provided between and in contact with a positive electrode and a light-emission layer. |
