Recent Progress in Polymeric LED — •Klaus Meerholz — Physikalische Chemie, Universität Köln, Luxemburgerstr. 116, 50939 Köln

Organic light emitting diodes (OLEDs) based on electroluminescent conjugated polymers are considered as a promising alternative for display and lighting applications, mainly due to their better compatibility with low-cost production techniques and large substrates. A challenge is multiple-layer deposition to improve the efficiency of the devices and, as a result, their lifetime.

This contribution summarizes recent trends in the field of OLED with an emphasis on solution-processed devices. We have in the past developed photochemically crosslinkable semiconductors for fabrication of complex multilayer OLED with a potential for eventually becoming organic lasers and RGB-pixelation [1-2].
