Abstract

Insoluble triplet-emissive layers were realized due to the introduction of an oxetane moiety into an orange-emitting iridium(III)-complex. Highly efficient and entirely solution processed multilayer devices were fabricated and the well-balanced charge injection and transport results in a maximum luminous efficiency of 18.4 cd A(-1) and a power efficiency of 14 lm W-1 at a brightness of 100 cd m(-2). These results compare favorably with vacuum-processed devices reported in the literature.
