The factors that govern the stereo- and regioselective cyclopolymerization of 1,6-heptadiynes with Rualkylidenes shall be elucidated. For this purpose, novel ruthenium-based initiators applicable to the metathesis-based cyclopolymerization of α,ω-diynes shall be synthesized. In addition, novel monomers, suitable for these purposes shall be designed and synthesized. The main focus of this project shall be devoted to mechanistic aspects of the cyclopolymerization process. The entire project will be supported by quantum chemical calculations. The final goal is to understand all prerequisites, whether catalyst or monomer related, for the controlled, living, stereo- and regioselective synthesis of poly(ene)s. Finally, in terms of materials science, the resulting polymers shall be briefly screened for their suitability to the area of conducting polymers. Despite a significant Peierls distortion that may well be expected for these polymers, priliminary data on conductivity are promising.

应阐明控制 1,6-庚二炔与 Ru 亚烷基的立体和区域选择性环聚合的因素。为此，应合成适用于 α,ω-二炔复分解环聚合的新型钌基引发剂。 ，应设计和合成适合这些目的的新型单体，该项目的主要重点应致力于机械方面。整个项目将得到量子化学计算的支持，最终目标是了解聚（烯）的受控、活性、立体和区域选择性合成的所有先决条件，无论是催化剂还是单体。就材料科学而言，应简要筛选所得聚合物是否适合导电聚合物领域，尽管这些聚合物可能会出现显着的佩尔斯失真，但电导率的初步数据。是有希望的。
