β-1,3-Glucans act as unique natural nanotubes, the featuresof which are greatly different from other natural or synthetic helical polymers. The origin mostly stemsfrom their strong helix-forming nature and reversible interconversion between single-strand random coiland triple-strand helix. During this interconversion process, they can accept functional polymers, molecularassemblies and nanoparticles...
The calixarene-fullerene interaction,which causes only a slight change in the absorptionspectra, has been substantiated by calorimetricmeasurements: the Δ H° values arecomparable with those obtained from the associationconstants estimated by a spectroscopic method. Furthermore, we determined the association constantbetween homooxacalix[3]arene and [60]fullerenederivatives with a porphyrin moiety by...
