Imidazolium-based receptors

Macrocyclic receptors containing two binaphthol groups with imidazolium-based linkers 38,39 (Fig. 12) were shown to undergo enantioselective fluorescence enhancement in the presence of d- and r-Trp in water, due to a rearrangement of the receptor conformation upon complexation [95]. [Pg.197]

A new imidazolium functionalised cholestane-based receptor has been synthesised and characterised by Kim et al. A binding study of receptor (22) with various anions was assessed by UV-Vis and fluorescence spectroscopy in dry CH3CN and aqueous CH3CN solutions. Receptor (22) showed the highest selectivity toward H2PO4 which was a biologically vital... [Pg.87]
