Abstract

Abstract : We report the preparation of methylene bridged glycoluril dimer1 bearing two triptycene walls and its function as a host toward hydrophobic cations in water. Abstract : The strategic combination of the methylene bridged glycoluril dimer and triptycene skeletons delivers acyclic water soluble hybrid receptor1 which is analogous to cucurbit[6]uril. The molecular recognition properties of host1 toward hydrophobic cationic guests are investigated in detail by a combination of 1 H NMR spectroscopy and isothermal titration calorimetry (ITC) studies. The fluorescence emission of1 can be selectively and efficiently quenched upon the formation of1·26 and1·28 complexes.
