| 英文摘要 | A new neutral fluorescent chemosensor 5 based on a calix[4]arene tetraamide derivative has been synthesized. it exhibits high selectivity for h2po4- over a wide range of anions, and the selectivity for h2po4- is more than 2700-fold higher than for f-. in acetonitrile, the fluorescence intensity of 5 is efficiently enhanced about 130% [(i-i-0)/i-0] upon the addition of 5 equiv. of h2po4-. from the fluorescence titration experiments, the association constant for 5/h2po4- (1:2) was calculated to be 5.48 x 10(9)m(-2). furthermore, the h-1 nmr spectral and x-ray crystal studies suggested that multiple hydrogen-bonding interactions occur between 5 and h2po4-. |
