Hybrid Core-Shell Nanoparticles by "Plug and Play" Self-Assembly.

Supramolecular hybrid functional nanoparticles (NPs) can be obtained via the colloidal tectonics approach provided that multiple interactive molecular tectons are used. Herein, the programmable synthesis of novel hybrid core-shell nanoparticles via the following sequential steps is reported: (i) complexation of 1-decanol by the β-cyclodextrin (β-CD), (ii) spontaneous self-assembly into CD NPs, (iii) adsorption of polyoxometalate anions, PW12 O40 3- , on the polar neutral interface of the CD NPs. Such an approach paves the way for the design of novel and original materials and systems.
