Colorimetric sensing of anions in aqueous solution using a charge neutral, cleft-like, amidothiourea receptor: Tilting the balance between hydrogen bonding and deprotonation in anion recognition
(2008)The design, synthesis and physical evaluation of 1, a visible colorimetric `naked eye? pyridyl based bis-amidothiourea sensor for anions, is described. This charge neutral sensor gives rise to significant changes in the ... -
Crystallographic, 1H NMR and CD studies of sterically strained thiourea anion receptors possessing two stereogenic centres
(2009)The synthesis and structural characterisation of three chiral bis-naphthalene thiourea receptors (1?3) derived from (R)-(+)-1-(1-naphthyl)ethylamine and (S)-(?)-1-(1-naphthyl)ethylamine are reported along with spectroscopic ...
