摘要：

Sulfonated indolinespirobenzopyran (SP-SO3-) was intercalated into the Mg/At or Zn/Al layered double hydroxides (LDHs) in the presence of toluene-p-sulfonic acid (PTS). The new intercalates exhibited reversible photoisomerization between SP-SO3- and merocyanine (MC). The presence of PTS was critical for the reversible photoisomerization. MC was very stable and the rate constant of decolorization was <9x10(-7) s(-1). SP interacted with non-polar portions between the layers although MC interacted with the polar interior surface of the LDH.
