Synthesis and characterisation of photo-crosslinkable TPD derivative hole-transport material

摘要

One of the approaches to improving the recombination of electrons and holes in the emitting layer of organic light emitting diodes (OLEDs) is to produce a multilayer OLED comprising a hole-transporting layer, an electron-transporting layer and a light emitting layer. This brief paper investigates the use of oxetane functionality attached to a hole-transport material as a photopolymerisable material. Oxetanes undergo fast polymerisation with high conversion and limited cracking.
