A pair of chromophores with donor-acceptor properties,4-methoxyphenylacetic acid(4-MAA) and 2-naphthalene sulfonic acid(2-NSA),were intercalated into the layered double hydroxide(LDH),[Mg0.66Al0.34(OH)2](CO3)0.17.0.67H2O by the method of ion-exchange procedures in ethylene glycol.The obtained co-intercalation compounds were characterized by X-ray diffraction,infrared and thermogravimetry techniques.The photochemical properties of the obtained compounds were studied by UV-Vis absorption and fluorescence spec...
