Exploitation of synthetic methods for highly conjugated compounds and evaluation of their properties

我们主要以周环的环化还原为关键步骤，合成了π-体系稠合卟啉低聚物、双硫卟啉、环[n]吡咯、芘、[5]螺烯、bisBODIPY和萘[2，3-f]异吲哚，并分析了它们的电子性质。π-体系稠合卟啉低聚物的双光子吸收性质被证明不是受其π体系的数目的影响，而是主要受其π体系的形状的影响。已经探索了仅在NIR区域中具有强吸收的稳定的bisBODIPY。

We investigated synthesis of pi-system-fused porphyrin oligomers, bisthiaporphyrin, cyclo[n]pyrroles, picenes, [5]helicenes, bisBODIPYs, and naphth[2,3-f]isoindoles mainly based on the pericyclic cycloreversion as the key step and analyzed their electronic properties. The two-photon absorption property of pi-system-fused porphyrin oligomers is proven to be affected not by the numbers but mostly by the shapes of their pi systems. Stable bisBODIPYs bearing strong absorptions only in the NIR region have been explored.
