摘要：

Giving the guest-dependent and enhanced interlayer distance, the intercalation of 1,5-, 2,6- and 2,7-naphthalenedisulfonates(abbreviated as N15DS, N26DS and N27DS, respectively) between layers of synthetic hydrotalcite and a hydrotalcite-like compound is observed in X-ray powder diffraction (XRD) patterns. Intercalated compounds are also characterized by means of X-ray photoelectron spectroscopy (XPS), diffuse reflection spectroscopy (DRS) and by DTA/TG thermal analysis. Dimensions are compared between the distance and the guest anion size which is estimated in a semiempirical MO calculation. Results are elucidated by the existence of the guest dianion which bridges between two adjacent layers of double-hydroxides.
