摘　　要：从一个含有烯基的中心核分子开始,重复进行硅氢化作用和烯基化作用的过程可以获得以硅原子作为支化点的碳硅烷树形分子。碳硅烷树形分子在催化化学、主客体化学、电化学、液晶高分子化学等领域有着广泛的应用。Starting from a core molecule possessing alkenyl groups and repeating the hydrosilylation step and alkenylation step, a carbosilane dendrimer with Si-atoms as branching pointing was obtained. Most of carbosilane dendrimers exhibit high flexibility, and the use of Si as branching connectivity permits one to vary the branching multiplicity between 2 and 3, allowing one to tailor the density of the structure. The application of carbosilane dendrimers in catalysis, host-guest chemistry, electrochemistry, liquid crystalline polymer chemistry were described in this paper. Progress in this area may eventually lead to novel materials, particularly tough coating, lubricants, adhesives as well as fluids with unusual rheological properties.
