title: A new fluoride selective fluorescent as well as chromogenic chemosensor containing a naphthalene urea derivative.
abstract: A new naphthalene derivative containing a urea group at the 1,8-position of naphthalene was synthesized and showed a unique absorption and fluorescence peak with a fluoride ion. Calculations suggested that a new peak was attributed to the increased anion character of urea nitrogen due to the strong interaction of the fluoride and N-H protons.
