Abstract

We report on the development of a supramolecular nanocarrier concept
that allows for the encapsulation and separation of small apolar
molecules from water. The nanocarriers consist of shell‐by‐shell‐coated
nanoparticles such as TiO2 and ferromagnetic Fe3O4. The first ligand shell is provided by covalently bound hexadecyl phosphonic acid (PAC16)
and the second shell by noncovalently assembled amphiphiles rendering
the hybrid architecture soluble in water. Agitation of these constructs
with water containing the hydrocarbons G1G4, the fluorescent marker G5,
the polychlorinated biphenyl PCB 77, or crude oil leads to a very
efficient uptake (up to 411 %) of the apolar contaminant. In case of the
hybrids containing a Fe3O4 core, straightforward
phase separation by the action of an external magnet is provided. The
load can easily be released by a final treatment with an organic
solvent.
