<p>PURPOSE:To obtain a new compound having stable film-producing property as a material for organic electroluminescent elements, especially useful as a luminous material, an electron transporting material, etc., and having long-term storage stability. CONSTITUTION:This compound of formula I [A is a (substituted)aromatic or a (substituted)aromatic heterocycle; R is H, a halogen, an (substituted)alkyl, a (substituted)alkoxy or hydroxyl] is obtained by reacting an acid halide compound of formula II (X is a halogen) with a tetrazole compound of formula III or formula IV. Furthermore, the acid halide compound is synthesized by treating a carboxylic acid compound of formula V with a halogenating agent such as thionyl chloride or phosphorus pentachloride.</p> |
