The proposed research will develop catalytic routes to polyaminoboranes, a new class of polymers that have been prepared as an unanticipated spin-off from a recent EPSRC grant. We aim to exploit this preliminary breakthrough to develop these new materials and, crucially, to discover what properties they possess. The proposed work is essential if these materials are to have widespread impact. Polyaminoboranes have excellent potential and are readily accessible from cheap starting materials (amine-borane adducts). Synthetic development and improved catalysts will allow access to a wide range of materials with different properties, for which exciting potential applications can be envisaged. We will also target polyiminoboranes, BN analogs of polyacetylene, which have been predicted to possess interesting properties as a result of significant electron delocalisation.

拟议的研究将开发聚氨基硼烷的催化途径，聚氨基硼烷是一种新型聚合物，是最近EPSRC资助的意外衍生产品。我们的目标是利用这一初步突破来开发这些新材料，最重要的是，发现它们具有什么特性。如果这些材料要产生广泛的影响，拟议的工作是必不可少的。聚氨基硼烷具有很好的潜力，而且很容易从廉价的原料（胺硼烷加合物）中获得。合成发展和改进催化剂将允许获得具有不同性质的广泛材料，可以设想令人兴奋的潜在应用。我们还将针对聚亚胺硼烷，聚乙炔的BN类似物，由于显着的电子离域，它被预测具有有趣的性质。
