WebLigand 1 contains a resorcin [4]arene 24,25 macrocycle comprised of four phosphate substituted aromatic units. The macrocycle shows some degree of flexibility, as the structure rapidly interconverts between two equivalent boat conformations, but full rotation is prevented through its alkyl feet (Fig. S18–S20, ESI † ). WebThis result suggests that phosphate groups on the polymer have a higher affinity to the surface of nanoparticles. It is important to emphasize that the incomplete ligand exchange greatly influences the colloidal stability in aqueous media of final polymer coated UCNPs owing to the presence of hydrophobic oleic acid molecules.
