In this study Mg/Al layered double hydroxides (LDHs) and organo-modified chiral LDHs were synthesized in one step under green conditions. Co-precipitation reaction of the Al(NO3)(3) center dot 9H(2)O, Mg(NO3)(2) center dot 6H(2)O and different biocompatible N, N-(pyromellitoyl)-bis-L-amino acids was carried out in aqueous solution in a short time by an ultrasonic technique. Field emission scanning electron microscopy and transmission electron microscopy techniques showed that the resulting products have good crystallinity and uniform morphology. The presence of the bioactive surfactants in the interlayer space of LDH was confirmed by Fourier transform infrared spectroscopy, X-ray diffraction (XRD) and thermogravimetry analysis techniques. As expected, the positions of the basal reflections in the XRD patterns of modified samples are shifted to higher d value indicating the expansion of the interlayer distance. Thermal properties were investigated by the thermogravimetric analysis technique.
