a Molecular structure of various nucleotides. b CD and CPL activities triggered by the co-assembly process of Ag40 in DCM with UMP (dissolved in DMSO) and H2O, accompanied by an aggregation-induced luminescence enhancement process visible to the naked eye under visible (left) and UV (right) light irradiation. c Emission spectra of different stages (initial, Ag40; intermediate, Ag40 + UMP (M); final, Ag40 + UMP + H2O, abbreviated as Ag40 + UMP) in the recognition (λex = 430 nm). d Column chart of the emission intensity of the PL, CD, and CPL spectra for Ag40, Ag40 + H2O, and the co-assemblies with nucleotides. e Time-dependent CD spectra of the co-assemblies formed by Ag40 (1 × 10‒5 mol L‒1) in 3 mL of DCM with 20 μL of UMP (3 × 10‒2 mol L‒1) in DMSO and 20 μL of H2O. Interval: 4 min. f CD spectra of the co-assemblies formed by Ag40 (1 × 10‒5 mol L‒1) in 3 mL of DCM with 0‒50 μL of UMP (3 × 10‒2 mol L‒1) in DMSO and 20 μL of H2O. Interval: 5 μL. g CPL spectra of the co-assemblies formed by Ag40 (1 × 10‒5 mol L‒1) in 3 mL of DCM with 0‒50 μL of UMP (3 × 10‒2 mol L‒1) in DMSO and 20 μL of H2O. Interval: 5 μL.
