Quinoline derivative and use of same

摘要

Quinoline compound, zinc halogenide complex and zinc complex suited for use in an electro-luminescence element, a fluorescent material and an ultraviolet absorption material, and a preparation process for these compounds are described. These compounds and a tautomer of the same has a strong luminescent intensity and is used for an EL material, the compound of zinc halogenide complex and zinc complex and a tautomer of the same has absorption at a wave length of 400nm or less and is used for an ultraviolet absorption material, and further the quinoline compound and a tautomer has a strong luminescent intensity and is used for a fluorescent material. The zinc halogenide complex and zinc complex can be prepared by each other related preparation processes directly from a quinoline derivative and a phthalimide derivative, or by way of the quinoline compound which is obtained from these derivatives.
