Derivative of Anthraquinone capable of using Cu II selectively and manufacturing method thereof

摘要

PURPOSE: A derivative of anthraquinone capable of using Cu(II) selectively is provided to sense copper ions using fluorescence color properties and to exhibit high selectivity in the copper ions. CONSTITUTION: A derivative of anthraquinone is represented by formula 1. A method for preparing the derivative of anthraquinone comprises the following steps of: mixing 1-chloroantraquinone and ethylenediamine in an organic solvent to obtain a first solution; mixing the first solution and phenylisothiocyanate in the organic solvent to obtain a second solution; agitating the second solution, evaporating it, and dissolving it in the organic solvent; and washing, drying, and filtering the dissolved mixture, evaporating the same at reduced pressure to obtain the derivative of anthraquinone.
