a Chemical structure of p-CN-Au3. b Partial 1H NMR spectra of p-CN-Au3/R-THFA in d6-DMSO with different R-THFA molar ratio. c FT-IR spectra of p-CN-Au3, R-THFA and p-CN-Au3/R-THFA (3 equiv.) assembly. d ESP mapping of p-CN-Au3 and R-THFA. e Proposed C-H ∙ ∙ ∙ O and C-H ∙ ∙ ∙ N interactions between p-CN-Au3 and R-THFA. f PXRD patterns of p-CN-Au3, R-THFA and p-CN-Au3/R-THFA (1 and 3 equiv.) assemblies. g Plausible co-assembly mechanism of p-CN-Au3/R-THFA from DMF solution.
