Abstract

Robust, conformal, adherent, pinhole-free transport layers for OLEDs have been prepared by crosslinking the proven charge-transporting core structure, triarylamine, via siloxane connections (see Figure and also Cover). Concomitant spin-coating, followed by curing, yields hole transport layers that give efficient LED structures with remarkably low leakage currents.
