N2 - A novel heteroacene with an aroyleneimidazophenazine moiety (1) has been successfully synthesized and characterized. Compound 1 can selectively detect CN- and F- over another ten anions (Cl-, Br-, I-, Ac-, H2PO4 -, NO3-, SO42-, ClO 4- and BF4-, PF6 -) in mixed solvents with multiple responses including fluorescent "turn-off", colorimetric and near-infrared absorption signaling. The interactions between 1 and CN-/F- have been investigated through UV-vis and fluorescence experiments, and the results suggest that the anion-π interactions between 1 and CN-/F- might be reversible processes upon the addition of Cu2+ and Fe3+ cations.
