Abstract

The best part of synthetic organic chemistry is the ability in creating new molecules, which would become lead compounds as for example, catalysts, materials, and pharmaceuticals in future science and technology. My research group has been working on this aspect and especially focusing on molecules related to highly reactive or strained species. I am going to introduce you such two examples in this seminar.

The first example is molecules controlling radical polymerization. Although radical polymerization is the most versatile and widely used technique in producing polymer materials in industry, control of molecular structures has been difficult so far. We have designed and synthesized several organotellurium compounds, which are highly versatile as controlling agents for “living” radical polymerization (Figure 1). Synthesis of structurally well-controlled polymers based on the photo-activation of organotellurium compounds will be mainly discussed.1)

The second example is hoop-shaped conjugated p-molecules, especially cycloparaphenylenes (CPPs), which is a simplest structural unit of armchair carbon nanotube (Figure 2). Due to their aesthetic structure and potential applications in molecular electronics, CPPs have attracted great deal of attention for more than a half century. However, despite of their rather simple structure, synthesis of them has been a significant challenge. In this presentation, a new synthetic method of CPPs will be discussed.3)
