The project deals with the development of a novel polymerization method for preparation of polyarenes. The method does not need any transition metals and allows for formation of oligoarenes, a compound class which has found importance in materials science. As monomer building blocks aryl Grignard reagents bearing an anionic leaving group will be used. Reactions proceed via a strongly alternating radical/anionic process. Such alternating radical/anionic polymerizations are currently not explored. The presented polymerization process belongs to the class of chain growth polymerizations. In the proposal various low temperature initiation processes are suggested. In addition, various monomers will be prepared and tested in the novel SRN1-polymerization. Analysis of the polyarenes will be conducted by gel permeation chromatography, NMR spectroscopy, mass spectrometry and the photophysical properties of the novel materials will be investigated. An additional important point is the development of processes which allow for end group control. Along this line methods and end capping reagents will be developed.

该项目涉及开发一种制备聚芳烃的新型聚合方法。该方法不需要任何过渡金属，并允许形成低聚芳烃，这是一种在材料科学中具有重要意义的化合物。将使用带有阴离子离去基团的芳基格氏试剂作为单体结构单元。反应通过强烈交替的自由基/阴离子过程进行。这种交替的自由基/阴离子聚合目前尚未探索。所提出的聚合方法属于链增长聚合类。在建议中，提出了各种低温引发工艺。此外，各种单体将在新的SRN 1聚合中制备和测试。将通过凝胶渗透色谱法、核磁共振光谱法、质谱法对聚芳烃进行分析，并对新型材料的物理化学性质进行研究。 另一个重要的方面是开发允许端基控制的工艺。沿着这条线的方法和封端试剂将被开发。
