  Conducting polymers such as polypyrrole and polythiophene offer a new approach to the design of modified electrodes and sensors. In the current work, the electrochemical and chemical polymerisation of tetra(pyrrol-1-yl)silane is described. Resultant polymers with different anions have been characterised by electrochemical methods, XPS and microanalysis. Molecular geometry calculations suggest that both inter- and intra-molecular couplings are present in the film. Crosslinking of the polymeric matrix via β-linkages will result in a three-dimensional structure with a concomitant reduction in the degree of conjugation, accounting for the low film conductivity (σ ca. 10–6 S cm–1).Preliminary results show that poly[tetra(pyrrol-l-yl)silane] is a promising material for the fabrication of gas sensors. It is unexpectedly sensitive to ammonia and trimethylamine gas when compared with polypyrrole and poly(N-methylpyrrole) prepared in a similar fashion.

  导电聚合物（如聚吡咯和聚噻吩）为改性电极和传感器的设计提供了新的方法。在目前的工作中，描述了四（吡咯-1-基）硅烷的电化学和化学聚合。通过电化学方法、XPS和微分析对具有不同阴离子的聚合物进行了表征。分子几何计算表明，薄膜中存在分子间和分子内偶联。通过β键交联聚合物基质将形成三维结构，同时共轭程度降低，这解释了薄膜的低电导率（σ ca. 10–6 S cm–1）。初步结果表明，聚[四（吡咯-l-基）硅烷]是制造气体传感器的有前途的材料。与以类似方式制备的聚吡咯和聚（N-甲基吡咯）相比，它对氨气和三甲胺气体的敏感性出乎意料。

  Amino derivatives of linear and branched tri- und tetrasilanes R2N-H2Si(SiH2)SiH2-NR2 H3SiSiHNR2SiHNR2SiH3, R2N-H2SiSiH2SiH2SiH2-NR2 und (R2N-H2Si)2SiHSiH(SiH2-NR2)2 with R = Et, SiMe3 are formed by the reaction of the corresponding bromooligosilanes with suitable amines or alkali metal amides. Product distribution and yields are strongly influenced by the nucleophilicity of the amino reagent and by the structure of the SiSi-backbone. The structures proposed for the aminopolysilanes thus prepared are proved by Si-29-, H-1-NMR- and MS-investigations.
