A new approach of fabricating supramolecular nanoparticles generated by self-assembly polyrotaxanes for antitumor drug delivery has been reported. Cinnamic-acid-modified poly(ethylene glycol) chains were threaded in α-cyclodextrins to form polyrotaxanes. The polyrotaxanes self-assembled supramolecular nanoparticles. The morphology of the nanoparticles was changed from nanovesicle to micelle aft...

A modular and hierarchical self-assembly strategy using block copolymer blends (AB/B’C) with tunable supramolecular interactions is reported. By combining supramolecular assembly of hydrogenbonding units with controlled phase separation of diblock copolymers, highly ordered square arrays or hexagonal arrays of cylindrical domains were obtained formixtures of poly(ethylene oxide)-b-poly(styrene-...

Two donor-acceptor copolymers, P1 and P2, containing the novel donor component benzo[2,1-b:3,4-b':5,6-c″]trithiophene were synthesized. Both polymers show small π-stacking distances (0.35 nm for P1 and 0.37 nm for P2) due to the use of the disklike-shaped donor unit. However, they exhibit remarkable differences in supramolecular organization, film microstructure, and transistor performance. Ind...

This Feature Article reports on the controlled formation and structure– functionality aspects of vacuum-deposited self-assembled organic and metal-organic networks at metal surfaces using ditopic linear and nonlinear molecular bricks, namely di-carbonitrile polyphenyls. Surface confi ned supramolecular organization of linear aromatic molecules leads to a fascinating variety of open networks. Mo...

We report an experimental study on the confinement of oligothiophene derivatives into single-walled carbon nanotubes over a large range of diameter (from 0.68 to 1.93 nm). We evidence by means of Raman spectroscopy and transmission electron microscopy that the supramolecular organizations of the confined oligothiophenes depend on the nanocontainer size. The Raman Radial Breathing Mode frequency...

The type III secretion system of Salmonella typhimurium directs the translocation of proteins into host cells. Evolutionarily related to the flagellar assembly machinery, this system is also present in other pathogenic bacteria, but its organization is unknown. Electron microscopy revealed supramolecular structures spanning the inner and outer membranes of flagellated and nonflagellated strains...
