Synthesis and application of carbosilane dendrimer

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.
