Creation of novel π-conjugated molecules is an important research topic. I describe in this account an approach to this aim that is based on the use of the distorted conformation of porphyrins. Planarization of distorted molecules enables the synthesis of heteroatom-containing porphyrin derivatives. Furthermore, dearomatization reaction proves effective to construct distorted conformations from planar π-conjugated molecules under mild reaction conditions. According to this protocol, we have succeeded in the synthesis of heteroatom-containing curved-π conjugated molecules that had never been achieved by conventional protocols. In particular, a nitrogen-embedded buckybowl is the first example of a buckybowl having a heteroatom in its central position, which exhibits unique properties due to the incorporation of the heteroatom in its curved π-surface.

基于扭曲结构开发卟啉及其类似物的合成方案——SPP/JPP 青年研究员奖论文

小说创作π共轭分子是一个重要的研究课题。我在本文中描述了一种实现这一目标的方法，该方法基于使用卟啉的扭曲构象。扭曲分子的平面化能够合成含杂原子的卟啉衍生物。此外，去芳构化反应被证明可以有效地从平面构建扭曲的构象π-在温和反应条件下的共轭分子。根据该协议，我们成功合成了含杂原子的弯曲-π传统方案从未实现过的共轭分子。特别是，嵌入氮的 buckybowl 是在其中心位置具有杂原子的 buckybowl 的第一个例子，由于杂原子在其弯曲处的结合而表现出独特的性质π-表面。
