Tristriazolotriazines (TTTs) with a threefold alkoxyphenyl substitution were prepared and studied by DSC, polarized optical microscopy (POM) and X-ray scattering. Six pentyloxy chains are sufficient to induce liquid-crystalline behavior in these star-shaped compounds. Thermotropicproperties of TTTs with varying substitution patterns and a periphery of linear chains of different lengths, branching

Single-wall carbonnanotubes (SWNTs) were functionalized by oligomeric species containing derivatized pyrenes. Absorption and emission properties of the pyrene moieties tethered to the functionalized SWNTs were studied in homogeneous solution. The absorption spectra suggest no significant ground-state complexation between the pyrenes and nanotubes. The fluorescence and fluorescence excitation results

The invention relates to amphiphilic Janus dendrimers which may form nanoparticles. The invention also relates to methods of inducing an adaptive immune response in a subject comprising administering to the subject an effective amount of a composition comprising at least one nucleoside-modified RNA encoding at least one antigen and at least one amphiphilic Janus dendrimer and to methods of delivering an agent to a subject in need thereof, said method comprising the step of delivering to the subject a composition comprising an agent encapsulated by a nanoparticle.
