Optical switching of self-assembly and disassembly of noncovalently connected amphiphiles.

Self-Assembly and Stimuli Responsive Disassembly of Dendritic and Oligomeric Amphiphiles

Assembly-disassembly switching of self-sorted nanotubules forming dynamic 2-D porous heterostructure.

We report the pH-driven formation of a dynamic 2-D porous heterostructure through assembly-disassembly switching of the stacked macrocycles of nanotubules and their subsequent spreading on the surfaces of a self-sorted sheet assembly in a hierarchical co-assembly. The 2-D ordered porous heterostructure is able to discriminate spherical C60 from flat coronene through shape selective adsorption.

A Survey of Burst Assembly Algorithms for Optical Burst Switching (OBS)

A lot of research has focused on the need to develop an all-optical next generation network. That is, the development of a network where both transmission and switching are all performed in the optical domain. Optical Burst Switching (OBS) has so far received more attention than its predecessors for such a solution. Burst assembly is one the most crucial elements of OBS. The objective of this p...

Luminescent supramolecular soft nanostructures from amphiphilic dinuclear Re(I) complexes.

Luminescent metallo-surfactants based on highly emissive dinuclear Re(I) complexes have been synthesized combining the peculiar photophysical behaviour of this class of neutral hydrophobic complexes with new properties imparted by hydrophilic chains anchored on the coordinated chromophoric ligand. In solution, the resulting neutral amphiphiles tend to self-assembly in soft structures. The aggre...

The role of spacers on the self-assembly of DNA aptamer-amphiphiles into micelles and nanotapes.

The self-assembly of single-stranded DNA (ssDNA) aptamer-amphiphiles was influenced by the choice of spacer used to link the hydrophobic tail and aptamer headgroup. Aptamer-amphiphiles without spacers or with hydrophilic spacers formed globular micelles while amphiphiles with hydrophobic spacers formed bilayer nanotapes, which are the first such structures formed by DNA-amphiphiles.
