DESCRIPTION:Speakers: Eleonora Shtykova (1. IC RAS\, Moscow\, Russia\, 2. 
 MSU\, Moscow\, Russia)\nDendrimers are three-dimensional\, highly branched
 \, monodisperse macromolecules with a well-defined regular structure. They
  possess unique properties due to its size\, composition and controlled fu
 nctionalization. Among the variety of dendrimers\, carbosilane dendrimeric
  macromolecules attracted great attention for their reactive functional gr
 oups\, chemical inertness of the molecular skeleton and possibility of med
 ical and biological applications [1\, 2]. \nIn the present work three-dime
 nsional structure of monodisperse carbosilane dendrimers of zero\, third a
 nd sixth generations were studied by small-angle X-ray scattering (SAXS) i
 n hexane solution. Using modern methods of SAXS data interpretation\, incl
 uding procedure of ab initio modeling\, spherical shape and internal archi
 tecture of the dendrimers were revealed depending on the generation number
  and on the number of cyclosiloxane end groups constituting a shell of the
  macromolecules. With the help of a computer simulation a possibility of s
 hape reconstruction of the dendrimer molecules in clusters has been consid
 ered\, and the analysis of the intermolecular interaction of the dendrimer
 s in solution was performed applying the latest developments of the method
  of molecular tectonics.\n\nThis work was supported in part by Russian Fou
 ndation for Basic Researches (projects 16-03-00379 and 16-03-00375)\nRefer
