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.

多面敏技术是各种功能材料的非常重要的合成方法。然而，它太简单的键形成过程通常迫使我们设计复杂的单体，以制备具有高级性能和功能的聚合物。作为另一种方法，我们一直在研究新型三组分多浓度过程的开发和应用。在该研究项目中，开发了一类新的三组分多面积过程及其在合成具有先进功能（例如有机溶液中溶解度）合成中的应用中的应用。例如，通过具有功能性部分的卤代苯乙烯和亲核粒子的三组分多敏，制备了具有独特功能的聚（芳基乙烯）S的合成。因此，可以根据亲核器的性质产生具有独特功能的π共轭聚合物。同样，可以在苏木 - 米约拉拉偶联反应等耦合过程中使用乙烯烯或氯苯二烯作为第三个成分，可以通过使用乙烯烯或诺伯二烯作为第三个成分来建立新的三组分多偏敏过程。从这些聚合系统中，可以通过简单单体制备具有新的主链结构单元的π共轭聚合物。发现某些所得聚合物表现出独特的功能，例如溶剂化发光特性。
