Nicola Armaroli and co-workers from CNR-ISOF, Bologna, Italy, and Davide Bonifazi and colleagues from the Universitŗ di Trieste, Italy, and the University of Namur, Belgium, have shown that - conjugated molecules bearing complementary hydrogen bonding sites can self-organise into complex nanostructures, which resemble natural micellar systems.
Nature creates spectacular nanoarchitectures through specific supramolecular assemblies of various components. Complementary hydrogen bonds are often utilised, which leads to the optimization of solvophilic interactions.
The use of hydrogen bonding also enables the tuning of the size and shape of the nanoparticles. The complementary hydrogen bonds promote self-organisation of the nanoparticles into uniform aggregates, and also enable a morphological change to occur from nanoparticle to vesicles.
