  • Nanoscale chirality generated in zinc(II) orthophosphate clusters: evidence by vibrational circular dichroism

    Sumio Aisawa, Nami Horiguchi, Chika Chida, Jing Sang, Hidetoshi Hirahara, Akihiko Yamagishi and Hisako Sato

    Layered zinc(II) hydroxides (LZH) intercalating the deprotonated forms of R-(−) or S-(+)-1,1’-binaphthyl-2,2’-diyl hydrogenphosphate (denoted as R- or S-BNDHPH, respectively) were prepared from Zn(NO3)2 atpH 5 and 60 °C by the mixing method. The obtained hybrid compounds (denoted as R- or S-BNDHP−/LZH, respectively) were heated from room temperature up to 800 °C under nitrogen atmosphere. According to the thermal gravimetric/differential thermal analysis measurements, hydroxyl groups were dehydrated at 270–400 °C, followed by the decomposition of organic components at 420–600 °C. X-ray diffraction patterns and scanning electron microscopy images indicated that the final products were a mixture of α-Zn3(PO4)2, ZnO crystals and non-crystalline zinc(II) orthophosphates. Vibrational circular dichroism (VCD) spectra were recorded before and after calcination. Before calcination, R- or S-BNDHP−/LZH exhibited VCD peaks assigned to intercalated R- or S-BNDHP−. The calcined products exhibited several VCD peaks in the range of 900–1200 cm−1, maintaining the mirror-image relationship between R-BNDHP−/LZH and S-BNDHP−/LZH used as starting materials. The observed peaks were assigned to the PvO (symmetric), –POO−, and PvO (asymmetric) stretching vibrations of the PO43− groups. According to theoretical simulations, the observed VCD activity can be rationalised in terms of vibrational coupling between two PO43− groups in a generated chiral zinc(II) orthophosphate cluster.

  • SOLID-STATE VIBRATIONAL CIRCULAR DICHROISM FOR INTERCALATION COMPOUNDS OF LAYERED DOUBLE HYDROXIDES: TOWARDS DRUG DELIVERY SYSTEMS

    Hisako Sato, Sumio Aisawa, Akihiko Yamagishi

    Clay Science ( The Clay Science Society of Japan )  28 ( 1-2 ) 1 - 9   2024.07  [Refereed]

    International Conference Proceedings  Multiple authorship

    This review describes the application of solid-state vibrational circular dichroism spectroscopy (denoted as SD-VCD) to the intercalation compounds of layered double hydroxides (LDH’s). The hybrid compounds of chiral molecules and LDH are chosen as a main target. SD-VCD is employed to probe the conformation of an intercalated amino acid. Intermolecular interactions are studied from the VCD spectra on LDH samples co-adsorbing an amino acid and tartaric acid. Notably the enhancement of VCD signals occurs to provide evidence for the stereoselective interactions between the intercalated species. As a final goal, the analysis of a model drug tablet containing LDH is described by means of the microscopic scanning VCD method.
