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 Cu2+ and CN− ions in contrasting modes with detection limits of 5×10−6MolL−1 and 12×10−5MolL−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 Cu2+ ions and its quantification in human serum.
