The results show that the title compound is stable, the geometry calculated by AM1 is in good agreement with experimental results. The atoms of O(1),O(15), O(19),O(20) in the molecule bond easily with metallic atoms. So the title compound can form stable complex with rare earth metal ions.展开更多

Coordination of Hg2+ influences the electronic properties of the receptor at meso-position and alter the efficiency of nonradiative decay, hence increase the fluorescence intensity and red shift the absorption spectrum.展开更多
