项目摘要

Polycondensation technique is a quite important synthetic method for various functional materials. Nevertheless, its too simple bond formation process often forces us to design complicated monomers for preparation of polymers with advanced properties and functions. As an alternative approach, we have been working on the development and applications of novel three-component polycondensation processes. In this research project, the development of a new class of three-component polycondensation processes and their applications to the synthesis of π-conjugated polymers with advanced functions such as solubility in organic solvents were studied.For example, the synthesis of poly(arylene-vinylene)s having unique functions were prepared by the three-component polycondensation of haloarylallenes and nucleophiles having functional moieties. Consequently, π-conjugated polymers having unique functions could be produced depending on the nature of the nucleophiles. Also, a new three-component polycondensation processes could be established by use of acetylenes or norbornadiene as third components in the coupling processes such as the Suzuki-Miyaura coupling reaction. From these polymerization systems, π-conjugated polymers having new main chain structural units could be prepared from simple monomers. Some of the resulting polymers were found to exhibit unique functions such as solvatochromic luminescent properties.

缩聚技术是各种功能材料的一种非常重要的合成方法，然而，其过于简单的成键过程往往迫使我们设计复杂的单体来制备具有先进性能和功能的聚合物，作为一种替代方法，我们一直在致力于开发。新型三组分缩聚工艺及其应用在本研究项目中，开发了一类新型三组分缩聚工艺及其在合成具有先进功能的π-共轭聚合物中的应用。例如，通过卤代芳基丙二烯与具有功能部分的亲核试剂的三组分缩聚反应合成了具有独特功能的聚亚芳基-亚乙烯基，可以得到具有独特功能的π-共轭聚合物。此外，还可以通过使用乙炔或乙炔来建立新的三组分缩聚过程。降冰片二烯作为偶联过程（例如铃木-宫浦偶联反应）中的第三组分，可以从这些聚合体系中由简单单体制备具有新主链结构单元的π-共轭聚合物。例如溶剂化变色发光特性。
