Abstract

A novel carbazole derivative, N,N′-bis(9-ethyl-9H-carbazol-3-yl)- (ethane-1,2-diamine), has been synthesized by reacting 3-amino-9-ethylcarbazole with glyoxal and characterized by ¹H NMR, infrared spectroscopy, elemental analysis and mass spectra. The strong fluorescence emission at 438 nm of the derivative is effectively and selectively quenched by Cr³⁺. A 1:1 complex is formed between the carbazole derivative and Cr³⁺ and their association constant is 1.4 × 10⁴ L mol^-1. The results indicate that the carbazole derivative can provide a rapid, selective and sensitive response to Cr³⁺ in a linear dynamic range 1.0-20 μmol L^-1 with a limit of detection of 0.10 μmol L^-1 at pH 7.4. Common interferent ions do not show any interference with the Cr ³⁺ determination. It is anticipated that the carbazole derivative could be a good candidate probe and has potential application for Cr ³⁺ determination.
