Fig. 7: Schematic illustration and characterization of the photophysical properties of the host-guest complexes in PBS buffer solution.

Formed by R- or S-C[4]B with a−d ThT or e−h TO. b, f CD spectra, c, g emission spectra, d, h CPL spectra. In (b, d, f, h), host@guest binary complexes are formed by mixing 10 μM host with 10 μM guest, host@2guest homoternary complexes are formed by mixing 10 μM host with 20 μM guest, and the concentration of free host is 10 μM. In (c, g), host@guest binary complexes are formed by mixing 10 μM guest with 12 μM host, host@2guest homoternary complexes are formed by mixing 10 μM guest with 5.0 μM host, and the concentration of free guest is 10 μM.
