a CD spectra of p-CN-Au3 and THFA in DMF/H2O mixture with different fw. b CPL spectra of p-CN-Au3/THFA assemblies from DMF/H2O mixture with different fw. c FT-IR spectra of p-CN-Au3, R-THFA and p-CN-Au3/R-THFA (3 equiv.) assembly. SEM images of (d) p-CN-Au3/R-THFA and (e) p-CN-Au3/S-THFA from DMF/H2O mixture (fw 4/7). f PXRD patterns of p-CN-Au3, R-THFA and p-CN-Au3/R-THFA assemblies from DMF/H2O mixture with different fw. g Plausible assembly mechanism of p-CN-Au3/R-THFA assembly from DMF/H2O mixture.
