Abstract: We report a high-efficiency blue organic light-emitting diode (OLED) with a solution-processed emissive layer composed of an oligomeric host of poly[3-(carbazol-9-ylmethyl)-3-methyloxetane] (PCMO) that possesses high triplet-energy and high electron mobility. The device exhibited a current efficiency of 40.4 cd A(-1) with an external quantum efficiency (EQE) of 21.6% and power efficiency of 28.2 lm W(-1) at 230 cd m(-2) or 24.7 cd A(-1), 10.3%, and 15.5 lm W(-1) at 1 000 cd m(-2). The high efficiency may be attributed to the host possessing a high electron mobility and lower electron injection barrier, resulting in a more balanced carrier-injection. Moreover, the high electron-mobility favors the transport of electrons, resulting in a more balanced carrier-injection in the emissive layer. The device efficiency has been further enhanced to 42.6 cd A(-1) (22.9%, 29.7 lm W(-1)) at 124 cd m(-2) or 28.8 cd A(-1) (15.4%, 17.8 lm W(-1)) at 1 000 cd m(-2) by pre-heating the emissive solution at an elevated temperature before spin-coating
