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.
