Absorption and CD spectra. a Molecular structures of bilateral N-amidothioureas L,L-XA (X = H, F, Cl, Br, I) with labeled protons. b Absorption and CD spectra of L,L-XA in CH3CN. [L,L-XA] = 5 μM. c CD spectra of L,L-IA and D,D-IA in CH3CN solution and the solid state. For solution, [IA] = 5 μM, while the concentration of the solid CD sample is about 1.0 mg/400 mg KCl. d STM height image of L,L-IA at the CH3CN-HOPG interface with height profile along the red dashed line. Inset is the thickness of single cis-L,L-IA molecule along b-axis revealed by the crystal structures. [L,L-IA] = 1 μM
