摘要

Dendrimers are well defined, highly branchedmacromolecules that radiate from a central core and aresynthesized through a stepwise, repetitive reaction sequence thatguarantees complete shells for each generation, leading topolymers that are monodisperse. The synthetic proceduresdeveloped for dendrimer preparation permit nearly completecontrol over the critical molecular design parameters, such assize, shape, surface/interior chemistry, flexibility, and topology.Recent results suggest that dendritic polymers may provide thekey to developing a reliable and economical fabrication andmanufacturing route to functional nanoscale materials thatwould have unique properties (electronic, optical, opto-electronic, magnetic, chemical, or biological). In turn, thesecould be used in designing new nanoscale devices. In this paper,we determine the 3D molecular structure of various dendrimerswith continuous configurational Boltzmann biased direct MonteCarlo method and study their energetic and structural propertiesusing molecular dynamics after annealing these molecular representations.
