It is an object to provide a naphthobiscalcogenadiazole derivative which can be used as an intermediate for producing a naphthobiscalcogenadiazole compound having a fluorine atom introduced thereto. The naphthobiscalcogenadiazole derivative of the present invention is formula (I): (Wherein A 1 and A 2 are each independently an oxygen atom, a sulfur atom, a selenium atom or a tellurium atom; X 1 and X 2 are each independently a hydrogen atom, a halogen atom, a boronic acid group, or a boronic acid ester) Group, a boronic acid diamino naphthaleneamide group, a boronic acid N-methyliminoacetic acid ester group, a trifluoroborate base, or a triol borate base.). |
