Four novelstilbenederivatives containing 1,3,4‐oxadiazole unit have been synthesized in four steps with overall yields (27∼35%). The synthetic route involved one‐step installation of 2,5‐di‐p‐tolyl‐1,3,4‐oxadiazol via the direct coupling of p‐toluic acid with hydrazine hydrate promoted by PPA, benzylic bromination, conventional phosphonate formation, and Wittig‐Horner olefination.

An organic luminescence device capable of luminescence at a high efficiency, a high luminance and high durability is formed by a pair of electrodes comprising an anode and a cathode, and at least one organic layer disposed between the electrodes. The at least one organic layer includes at least one layer comprising a polymerized film of organic layer having at least two polymerizable double bonds.
