The present invention relates to macrocyclic compounds which are capable of selective binding to a target saccharide (e.g. glucose), making them particularly well suited for use in saccharide sensing applications. The present invention also relates to processes for the preparation of said compounds, to compositions and devices comprising them, and to their use in the detection of a target saccharide.

The synthesis and anion complexation properties of two hybrid cyclic peptide–thiourea cryptands have been studied. Receptors encapsulate sulphate via nine hydrogen bonds and show selectivity for this anion in solvent mixtures containing up to 20% H2O/deuterodimethyl sulphoxide. In this solvent mixture, chloride, bromide and acetate are encapsulated via six hydrogen bonds and with lower affinity than
Sulfur as halogenbondingacceptor has been inadequately characterized. A series of thiourea motifs containing tritopic receptors with halogen-bonding acceptor capabilities were synthesized in this study via tris(isothiocyanate) intermediates. Five new halogen-bonded complexes of these receptors were described, which were accepting highly linear C−I⋅⋅⋅S interactions from three different diiodotetrafluorobenzene
