A fluorescent heteroditopic host for ion pairs and zwitterionic species has been synthesized. Its affinity towards a series of anions, cations and ion pairs in acetonitrile has been assessed, and the spectroscopic response has been evaluated. Solid-liquid extraction experiments of inorganic salts, α-amino acids and γ-aminobutyric acid (GABA) into acetonitrile solutions were performed, and the resulting complexes were analyzed by UV/Vis absorption, fluorescence and 1H NMR spectroscopy. The discrimination patterns observed have been rationalized in terms of the molecular topologies of the host and guests. Catching two balls: A BODIPY derivative bearing two independent yet complimentary hosts for anions and cations displays distinct absorption and fluorescence signalling patterns for different alkali metal halides. The compound also recognizes zwitterionic compounds such as amino acids and γ-aminobutyric acid (GABA). Copyright

A bis(calix[4]pyrrole)-substituted BODIPY ditopic receptor 1 has been synthesised and characterised. The binding and sensing properties of 1 towards several aliphatic and aromatic dicarboxylates have been evaluated by using UV/Vis fluorescence and 1H NMR spectroscopy. The receptor strongly binds linear α,ω-dicarboxylates of appropriate lengths (C9 and C10) by acting as a cleft. For all dicarboxylates, the binding event is detected by a bathochromic shift in the UV/Vis spectra of the receptor and by strong quenching of its fluorescence. The bis(calix[4]pyrrole)-substituted BODIPY ditopic receptor 1 shows high affinity towards linear α,ω- dicarboxylates of appropriate lengths. The binding event is detected by a bathochromic shift in the UV/Vis spectra of the receptor and by a strong quenching of its fluorescence. Copyright
