Rh-SP dyad bearing rhodamine ( Rh) and spiropyran ( SP) moieties was prepared. Reversible photochromic reaction was observed between colorless and nonfluorescent c- Rh- SP and c- Rh- MC with purple color and red fluorescence. Rh- SP can act as a triple chemosensor for Al3+, HSO- 3, and CN-, by absorption and fluorescence spectral changes. The results show colorless solution and orange fluorescence with Al3+, red solution and bright orange fluorescence with HSO- 3, and yellow solution and weak green fluorescence with CN-.
