HOLE TRANSPORT IN ORGANIC POLYMERS WITH SILICON BACKBONE (POLYSILYLENES)

Silicon-backbone cyclic and linear oligomers and high molecular weight linear polymers, poly(organosilylenes), have unique properties that distinguish them from saturated carbon polymer analogues. In this paper the authors report on an interesting property of this class of polymers, hole injection from photoelectrodes, and hole transport. Surprisingly, polymers with exclusively sigma -Si-Si bonds can support substantial hole transport, as demonstrated by our preliminary data on films of several homopolymers and copolymers.
