Abstract

New carbazole based AIEE material is synthesized with fluoro group which shows ESIPT induced AIEE in H₂O:THF (80:20, v/v). The material selectively recognizes Cu^{2 +} and CN^- ions in contrasting modes with detection limits of 5 × 10^{- 6} Mol L^{- 1} and 12 × 10^{- 5} Mol L^{- 1} respectively and acts as a dual action chemosensor. The recognition of copper has also been observed in human serum, thus facilitating the detection of increased level of free Cu ^{2 +} ions and its quantification in human serum.
