摘要：

The structures of the first generation of phenyl-substituted and permethyl-substituted dendritic polysilanes (1G(Ph)(6) and 1G) have been established by single crystal X-ray diffraction. The dendrimer 1G has two types of conformations designated A (anti-like conformation) and O (orthogonal-like) in the chain of Si-Si bonds. However, 1G(Ph)(6) has an unprecedented new type of conformation, E, which has an intermediate torsion angle between A and O. (C) 1999 Elsevier Science S.A. All rights reserved.
