COUMARIN DERIVATIVES AND THE METHOD OF PREPARING THE SAME

摘要

PURPOSE: A coumarin derivative used as a chemical sensor and a method for preparing the same are provided to generate fluorescence and to improve performance of a chemical sensor. CONSTITUTION: A coumarin derivative is denoted by chemical formula 1. The coumarin derivative is prepared by reaction formula 1. A hydrogen sulfate in a sample ion is selectively detected using the coumarin derivative. The hydrogen sulfate ion is selectively detected by measuring the fluorescence intensity. A chemical sensor for detecting the hydrogen sulfate ion contains the coumarin derivative of chemical formula 1.
