Tunable Composition of Mixed Self‐Assembled Shell‐by‐Shell Structures on Nanoparticle Surfaces

The formation of mixed shell-by-shell (SbS) systems with tunable shell compositions is demonstrated by using molecular self-assembly driven chemical recognition motifs. Aluminum oxide nanoparticles (AlOx-NPs) act as template surface for a self-assembled monolayer (SAM) either partially fluorinated fluoroalkyl or alkyl chained phosphonic acid derivatives defined stoichiometric mixtures those. By providing an equimolar mixture corresponding and alkyl-chained amphiphiles in water, the stoichiometry underlaying SAM on NP-surface preferentially directs composition secondary self-assembly. assemblies studied high performance liquid chromatography fluorescence spectroscopy. concept allows NP-templated vesicle-like bilayer structures, even consisting orthogonal chain structures hydrophobic segregation.
