| Abstract: | Larger-rim functionalized tetraoxacalix2]arene2]triazine host molecules were efficiently synthesized through a fragment coupling followed by AlCl3-mediated deprotection/arylation protocol. Substituent effects, functions of counter cations on anion recognition in solution were systematically studied by means of fluorescence and NMR titrations. |
