Abstract:
Summary: Modern multilayer organic light‐emitting devices (OLED) are fabricated easily and at low cost by spin‐coating with subsequent crosslinking of the layers. For this purpose, a low‐molecular‐weight hole‐transport material based on triphenyl amines bearing crosslinkable oxetane groups was synthesized. Crosslinking of the spin‐coated layer was initiated with UV irradiation using an iodonium‐salt photoinitiator and was observed using realtime FT‐IR spectroscopy. Standard photolithography techniques can be used for structuring the material on the micrometre scale. An AFM image of the photopatterned bis‐oxetane‐functionalized low‐molecular‐weight hole‐transport material based on triphenyl amines synthesized here. image An AFM image of the photopatterned bis‐oxetane‐functionalized low‐molecular‐weight hole‐transport material based on triphenyl amines synthesized here.
