Polycarbosilanes exhibit desirable physiochemical properties such as high thermal stability, elastomeric behavior, diverse functional group tolerance, electronic delocalization, and ease of synthesis. New ceramic precursors, fire‐retardant materials, and flexible conducting polymers have been created using polycarbosilanes. Catalytic hydrosilylation provides a convenient synthetic route to these materials. With its tolerance of many functional groups, catalytic hydrosilylation offers one‐step syntheses of both aliphatic and olefinic polymers and dendrimers whose electronic properties can be tuned selectively. Copolymerization of conjugated diynes with compounds that contain the silole chromophore offers a route to new luminescent materials that have been applied to the detection of explosives and may be promising organic light‐emitting diode materials. An important feature of the silole materials is the Lewis acidity at silicon, which offers a function not often present in organic polymers.
