Supporting Information for Designer lyotropic liquid-crystalline systems containing amino acid ionic liquids as self-organization media of amphiphiles

1. General Procedures and Materials General Procedures. 1 H NMR and 13 C NMR spectra were obtained on a JEOL JNMECX400 at 400 and 100 MHz in DMSO, respectively. Chemical shifts of 1 H and 13 C NMR signals were quoted to (CH3)4Si (δ = 0.00) and DMSO (δ = 39.5) as internal standards, respectively. Elemental analyses were carried out on an Elementar Analytical vario EL3. The viscosity of amino acid ionic liquids was measured by a cone/plate viscometer (LVDV-1+, Brookfield). The thermal properties of amino acid ionic liquids were measured using a differential scanning calorimeter (DSC-6220, Seiko Instruments). The thermal properties of the liquid-crystalline mixtures were examined by a DSC using a Netzsch DSC204 Phoenix. The heating and cooling rates were 5 °C min -1 . A polarizing optical microscope Olympus BX51 equipped with a Linkam LK-600 hot stage was used for visual observation. Wide-angle X-ray diffraction (WAXD) patterns were obtained using a Rigaku RINT-2500 diffractometer with CuK radiation. Two-dimensional small-angle X-ray scattering (2D SAXS) patterns of the materials were also recorded using an image plate detector (R-AXIS DS3C).
