Polymers containing inorganic elements in the main chain structure are of current interest as a result of their unique properties. The development of a new polymerization reaction makes it possible to create organicinorganic hybrid polymers having a unique structure, which is difficult to construct by conventional structures. During the past decade, these synthetic obstacles have been overcome through many creative procedures. Organic conjugated polymers are of much current academic and technological interest due to their optical and electronic properties. Various types of main group element-containing conjugated polymers have been synthesized using silicon, nitrogen, and sulfur. This review focuses on recent development of the main group elementcontaining conjugated polymers, such as conjugated organo-silicon, germane, -tin, -boron, -phosphorous, -arsenic, -antimony polymers.
