(o-ethynylphenyl)acetyl chloride with design of a new synthetic strategy by Stillecoupling using functionalized organostannanes. The method affords excellent yields of the substituted naphthalenes and accommodates a wide variety of functional groups under mild conditions. Mechanistic studies show intramolecular cyclization as a major step following C–C bond coupling.

The present invention provides a novel anthracene derivative, a method for preparing the same, and an organic electronic device using the same. The anthracene derivative according to the invention can function alone as a light emitting host, in particular, as a blue host in an organic electronic device. Further, the anthracene derivative according to the invention can also function as a hole injecting or hole transporting material, an electron injecting or electron transporting material, or a light emitting material in an organic electronic device including a light emitting device. Therefore, the organic electronic device according to the present invention shows excellent characteristics in efficiency, drive voltage and stability.
