| Abstract |
Rhodamine dyes are widely used as colorimetric and fluorescent chemosensors for the detection of various metal cations, owing to their strong absorption and fluorescence in the visible region accompanying by the structural change from the nonfluorescent and colorless spirolactam ring-closed form to strongly fluorescent and pink-colored ring-opened form.
Coumarin is a fragrant organic chemical compound in the benzopyrone chemical class, It is a natural substance found in many plants. Coumarin, the water soluble and blue fluorescent (410~470 nm) dye, is used as a gain medium in some dye lasers, and as a sensitizer in older photovoltaic technologies.
Combining two fluorescent dyes of rhodamine and coumarin is expected to exhibit very interesting physical and chemical properties. We report here a rhodamine-coumarin dyad as a candidate of chemosensor for a specific metal cation. |
