Abstract
The azo dye based chemosensor 2 displays extremely good sensitivity and selectivity for Na+ over other physiologically important alkali and alkali earth metal ions in the 0.3–1.0×10−4 M concentration range as well as being pH independent above pH 3.9. This sensitivity coincides with the Na+ concentration range found in blood. The sensor exhibits almost 110 nm hypsochromic shift in the absorption spectrum upon Na+ detection, with a strong colour change from red to yellow in aqueous solution which is clearly visible to the naked eye even at low concentrations.
