A guanidine-based fluorescent receptor has been synthesised to study its binding behaviour towards anions (F-, Cl-, Br-, I- and AcO-). The two donor N-H bonds of the receptor do not point in the same direction; rather, one N-H bond is intramolecularly hydrogen-bonded with the carbonyl oxygen atom. The nature of the donor-acceptor (DA) arrangement induces moderate binding properties. The binding behaviour towards monocarboxylic acids (benzoic acid and phenylacetic acid) is also compared. The binding behaviour of receptor 1 towards the F- anion is higher among the anions studied, whereas in the case of monocarboxylic acid, the binding constant with phenylacetic acid is higher than benzoic acid.
