Study of assembly of arachidic acid/LDHs hybrid films containing photoactive dyes

New multifunctional materials obtained by the intercalation of anionic dyes into layered zinc hydroxide nitrate followed by dispersion into poly(vinyl alcohol) (PVA)

“…9c and 9e. Therefore, the intercalation of OG anions into the layered hydroxide salt enhanced its color intensiveness and color blue shifting, as already observed in other intercalation studies involving Tropaeolin 000 (orange I) into Zn-Al LDH [22], blue dyes (Niagara blue, Evans blue, and Chicago sky blue 6B) into Zn 2 Al LDH, dispersed in polystyrene [26] and methyl orange into LDH [33].…”

High adsorption capacity for dye removal by CuZn hydroxyl double salts

“…The other one of 2.027 nm suggested that partial MO was intercalated into the interlayer of CuZn-HDS due to the dimension of the long axis of MO (1.31 nm). 34 It was noticed that the intensities of the characteristic diffraction peaks for HDS were weakened after adsorption, indicating that the adsorption behavior of MO on CuZn-HDS influenced the crystallinity of HDS. Due to relatively poor crystallization of CuZn-1 compared with that of CuZn-2 and CuZn-3, the crystallization of CuZn-1 after adsorption was poor.…”

Insights into the Photophysics and Supramolecular Organization of Congo Red in Solution and the Solid State

“…Sun and co‐workers studied the intercalation (by ion‐exchange) of CR into arachidic acid/LDH hybrid films and concluded that the CR molecules formed head‐to‐tail J‐type aggregates with a tilt angle of 31° with respect to the sheet surface (estimated from polarized UV/Vis absorption spectra and low‐angle XRD) . This near‐horizontal (parallel to the layers) arrangement is markedly different from the inclined (tilt angle of ca.…”
