A simple and versatile procedure was developed for the synthesis of pyrazino[2,3-b]thieno[3,4-e]pyrazine derivatives with intramolecular charge transfer character. The compounds obtained exhibited a narrower band gap compared to those with one pyrazine bridge.
开发了一种简单且通用的方法来合成具有分子内电荷转移特性的吡嗪并[2,3-b]噻吩并[3,4-e]吡嗪衍生物。与具有一个吡嗪桥的化合物相比,所获得的化合物表现出更窄的带隙。
