  • Chapter
  • First Online:
Silicon Polymers

Part of the book series: Advances in Polymer Science ((POLYMER,volume 235))

Abstract

In this chapter different types of conjugated organosilicon materials possessing luminescent and/or semiconducting properties will be described. Such macromolecules have various topologies and molecular structures: linear, branched and hyperbranched oligomers, polymers, and dendrimers. Specific synthetic approaches to access these structures will be discussed. Special attention is devoted to the role of silicon in these structures and its influence on their optical and electrical properties, leading to their potential application in the emerging areas of organic and hybrid electronics.

Notes

  1. 1.

    Coordinated within the CIE 1931 color space chromaticity diagram. CIE – the International Commission on Illumination (abbreviation comes from French “Commission internationale de l’éclairage”).

  2. 2.

    An optical limitation is an optical transmittance that sharply decreases at high light levels and strongly attenuates the optical power of intense laser pulses.
