Fig. 4: MOPS assemblies derived from different NPP ligands.

UV–Vis absorbance spectra of the synthesized MOPS and their corresponding NPPs. Pin pinoresinol; QC quercetin; Lut luteolin; Cya cyanidin; GC glycitein; EA ellagic acid. The insets are photographs of the different MOPS aqueous solutions under ambient light (1) and UV light (2). The backgrounds are photographs of the main sources of the NPPs.
