Imidazoliummoieties incorporated into a macrocyclic molecular are of particluar interest for anion receptors, due to their strong and tunable hydrogen binding abilities.
Well designed macrocycliccalixborates were synthesized with high yield. They show high binding affinity for halides and oxoanions and therefore are excellent candidates for anion sensor applications.
• Simple synthesis route in two steps, very high yield (> 80%)
• Rigid structures with calix shape with variable size cavity
• High selectivity: tunable anion recognition by changing the aromatic (A) groups
• High association constant and highest association constant for Iodine (Ka= 1 900 000 M-1)
• Simple detection method using fluorescence analysis, mass spectroscopy
• Possible one step speciation of anions mixture
• Development of Calix-bib recognition element integrated into real sensor for specific analysis
• Possible co-development for anion trap for medical treatment
• Water environment control and analysis
• Medical diagnosis
• Environmental protection
