Abstract
Layered double hydroxides (LDHs) have attracted a great deal of attention owing to their structural anisotropy, anion-exchange capability and compositional flexibility and have been widely investigated as catalysts, adsorbents, anionexchangers, polymer additives, optical materials, and so on. The intercalation of chromophores into the interlayer galleries of LDHs has drawn considerable interest since it can result in a kind of functional pigments showing different photophysical and photochemical properties from the pristine chromophores due to the host-guest and guest-guest interactions. This paper reviews recent patents progress made for the synthesis and applications of LDHs based pigments. The potentional applications and the future development are also discussed.
