Dynamical and structural properties of dendrimer macromolecules. Theory, Computer Simulations, and NMR experiment. (the report based on habilitation thesis) Dynamical properties: This report will be presented the theory of dynamical properties of a dendrimer which describes the local mobility within the macromolecule. The developed theory is based on analytical calculations and the results of computer simulations. The main conclusions of the theory agree with the experimental data. Structural properties: It will firstly be shown by theoretical and experimental studies that hollow core inside dendrimer can be formed in the system of dendrimer-solvent. The developed theory is based on numerical calculations self-consistent field method, atomistic computer simulations and experimental NMR studies of carbosilane dendrimers.
