100 μm‐Order Patterning of Organic Semiconductor Layers Using a Thermally Converted Precursor Technique and its Application to Organic Light Emitting Diodes

An N,N′-di(naphthalenyl)-N,N′-di(naphthalen-2-yl)-benzidine (α,β-TNB) precursor is prepared that can be thermally converted into α,β-TNB, losing its solubilizing groups to produce an insoluble component in isopropanol. Narrow pixel arrays with widths of 100-180 μm are then formed by thermal conversion of the α,β-TNB precursor, providing an OLED performance comparable to those made by vacuum deposition.
