Abstract
A bis‐tryptophan tweezer was installed on a polyoxometalate (POM) surface via a bis‐amide covalent bond, yielding the enantiopure hybrid POM with C2 symmetry, as a result of the regioselective functionalization of decatungosilicate [γ‐SiW10O36]8– at the lacunary site. The combined polyanionic and receptor properties are instrumental for a POM‐driven solubilization and enrichment of single walled carbon nanotubes (SWCNTs) with diameter <1.1 nm, as demonstrated by Raman and UV/Vis‐NIR evidence, in agreement with the calculated energetics of the tryptophan tweezer–SWCNT interaction.
