Zn/Al layered double hydroxide (LDH) intercalated by an anionic phenoxyherbicide guest, 3-(4-methoxypheny) propionate (MPP) were prepared by ion-exchange method. Power XRD and FTIR shows that the MPP phenoxyherbicide were successfully intercalated into the LDH interlayer. The basal spacing for Zn/Al layered double hydroxide-3-(4-methoxyphenyl) propionate nanocomposite (LDH-MPP) was 18.7 Å - 20.5 Å for 0.015 M, 0.025 M, and 0.050 M of MPP, respectively. Thermal analysis shows that the thermal stability of MPP was improved by the intercalation into the LDH interlayer. The results were also supported by elemental analysis and the surface morphology of this nanocomposite.

A new layered-double hydroxide-3-(4-hydroxyphenyl) propionate (LDH-HPP) has been synthesized by intercalation of 3-(4-hydroxyphenyl) propionic acid (HPP) into Zn-Al-layered double hydroxide (LDH) by ion-exchange method. PXRD, FTIR, TGA/DTG, compositional studies and FESEM were used to characterize the synthesized nanocomposite. The intercalation of HPP into the interlayer gallery space of LDH was characterized by x-ray diffractogram showed expanded basal spacing of the value of 17.1 Å. The FTIR spectra of LDH-HPP nanocomposite synthesis by 0.025M HPP resembled a mixture of both FTIR spectra of HPP and LDH. Thermal analysis of LDH-HPP nanocomposite shows a better thermal stability as compared to the pure HPP, which proved that the intercalation of HPP into LDH interlayer enhanced the thermal stability of the HPP.

The intercalation of herbicide, 2,4,5-tricholorophenoxybutyrate (TBA) , into zinc-aluminium-layered double hydroxide (ZAL) for the formation of a new nanocomposite ZAT, was accomplished via anion exchange method. Due to the intercalation of TBA with ZAL interlayer domain, basal spacing expanded from 8.9Å in the ZAL to 23.3 Å in the ZAT. The percentage loading of TBA in the ZAT is 45.5 % (w/w). The FTIR spectra of the nanocomposite shows resemblance peaks of the TBA and Zn-Al-layered double hydroxide indicating the inclusion of TBA into the layered double hydroxide. Surface area of the resulting nanocomposite increased from 1.3 to 15.6 m2g-1with the nitrogen adsorption-desorption of type IV, indicating the mesopore type of material.

A new magnetic Fe3O4/MO-intercalated-LDH composite has been synthesized by combination of Fe3O4, layered double hydroxide (LDH) and methyl orange (MO). Fe3O4/Zn2CrLDH and Fe3O4/MO-intercalated-LDH were obtained via two-step microwave hydrothermal and anion exchange method. X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectroscopy and vibrating sample magnetometer (VSM) were conducted to characterize the as-prepared samples. The latter exhibited that basal spacing of Zn2Cr-LDH is 1.18 nm. The value of saturation magnetization (Ms) is 20.5 emu/g. In addition, the amounts of adsorbed MO reached 1.54 mmol/g. Therefore, the material shows several advantages for the removal of pollutants.

Some functional luminol derivatives with aromatic substituted groups have been designed and synthesized from the reaction of the corresponding aromatic acyl chloride precursors with luminol. It has been found that depending on the size of aromatic groups, the formed luminol derivatives showed different properties, indicating distinct regulation of molecular skeletons. UV and IR data confirmed commonly the formation of imide group as well as aromatic segment in molecular structures. Thermal analysis showed that the thermal stability of luminol derivatives with p-phthaloyl segment was the highest in those derivatives. The difference of thermal stability is mainly attributed to the formation of imide group and aromatic substituent groups in molecular structure. The present results have demonstrated that the special properties of luminol derivatives can be turned by modifying molecular structures of objective compounds with proper substituted groups, which show potential application in functional material field and ECL sensor.
