    Abstract

    The molecular inclusions of symmetrical tetramethyl-substituted cucurbit<参考文献原文>uril and 2-(butane-1,4-diyl)dibenzimidazolium dichloride were investigated by using electronic absorption spectroscopy and fluorescence spectroscopy.The experimental results reveal that the formation of host-guest inclusion complexes between TMeQ<参考文献原文> and SBB were formed with stoichiometry ratios of 1∶1 and 2∶1, The calculated binding constants are K(1∶1)=(4.79±0.01)×104 L·mol-1 and, K(2∶1)=(8.51±0.01)×1010 L2·mol-2 respectively based on the absorption spectrophotometric analysis, while the calculated binding constants are K(1∶1)=7.02×104 L·mol-1 and K(2∶1)=2.88×1010 L2·mol-2 respectively based on the fluorescence spectroscopy analysis. The values of K are reasonably consistent.
