ADIMET: A Tool for the Synthesis of Alkyne-Briged Polymers

本论文的研究重点是通过炔复分解反应制备聚对苯撑乙炔（PPE）。 目标将是合成具有大手性活性的PPE、携带聚合物或共轭侧链的PPE作为新型棒-螺旋聚合物和用于聚合物发光二极管的PPE-异质结构。 此外，PPE的绝对分子量将通过催化氢化从刚性棒转化为柔性线圈来确定。 此外，将开发合成方法，用于通过简单的原位催化剂或限定的钼碳炔的炔复分解获得聚二乙炔和与PPE和聚（对苯亚乙烯基）（PPV）的混合物。材料特性将被确定，聚合物将被开发用于器件应用，如LED，圆偏振LED和基于PPE的激光器件。南卡罗来纳州大学化学和生物化学系的Bunz博士说。 Bunz教授的工作重点是使用炔复分解合成新的和已知的共轭聚合物。 这些聚合物作为稳定的、可加工的和具有广泛潜在应用的发射半导体是有吸引力的。 该研究也是本科生，研究生和博士后学生的优秀培训基地。

The focus of this research is the preparation of poly(paraphenyleneethynylene)s (PPEs) via alkyne metathesis. The goal will be the synthesis of PPEs with large chiroptical activities, PPEs that carry polymeric or conjugated side chains as novel rod-coil polymers and PPE-heterostructures for use in polymeric light emitting diodes. Also, the absolute molecular weight of the PPEs will be determined by transformation from rigid rods into flexible coils by catalytic hydrogenation. Further, synthetic methodology will be developed for access to polydiacetylenes and hybrids with PPEs and poly(paraphenylenevinylene)s (PPVs) by alkyne metathesis with simple in situ catalysts or defined molybdenum carbynes. Materials properties will be determined and the polymers will be exploited for device applications such as LEDs, circularly polarized LEDs and PPE-based lasing devices.With this award, the Organic and Macromolecular Chemistry Program is supporting the research of Dr. Uwe H. Bunz of the Department of Chemistry and Biochemistry at the University of South Carolina. Professor Bunz will focus his work on using alkyne metathesis for the synthesis of both new and known conjugated polymers. These polymers are attractive as stable, processable and emissive semiconductors with a wide range of potential applications. The research is also an excellent training ground for undergraduate, graduate and postdoctoral students.
