2 A composition of hole transporting layer comprising crosslinkable double-bond and crosslinking agent comprising 2 or more thiol groups and use thereof

摘要

The present invention relates to a polymeric hole transport material comprising a first unit comprising a first hole transporting fragment and a second unit comprising at least one double bond capable of crosslinking including a second hole transporting moiety hole transporting material and a cross-linking agent containing two or more thiol groups. Also, the present invention provides a method of manufacturing an organic semiconductor device comprising at least one organic layer stacked, comprising: a first organic semiconductor material including two or more crosslinkable double bonds and a crosslinking agent containing two or more thiol groups A first step of applying the first organic layer composition to the substrate; A second step of applying light or heat to crosslink; And a third step of applying a second organic layer composition in the form of a solution on the formed first organic layer.
