Abstract
The present invention relates to a sensor comprising a resorufin compound having sulfite ion selectivity and a method for detecting sulfite ions using the same. More specifically, the resorufin compound may have outstandingly increased fluorescence intensity by a deprotection reaction that a levulinyl group is cleaved with a sulfite ion to be used as a selective fluorescence sensor of turn-on type, and also represent a chromogenic change to detect sulfite ions by naked eye.
