complexes were tuned by attachment of electron-withdrawing and -donating aryl groups through the Suzuki–Miyaura coupling reaction. Optimization studies of the borylation reaction and Suzuki coupling of protected benzothiazoles were performed to maximize the yields of the target compounds. The absorption, emission, and electrochemical properties of the newly synthesized complexes were found to correlate
双[2-(2-羟基苯基)苯并噻唑基]锌(II)配合物的电子性质通过Suzuki-Miyaura偶联反应连接吸电子和供电子芳基来调节。对受保护的苯并噻唑的硼酸化反应和 Suzuki 偶联进行了优化研究,以最大限度地提高目标化合物的产率。发现新合成配合物的吸收、发射和电化学性质与所连接的芳基的电子性质相关。虽然 LUMO 能级对取代基的依赖性较小,但 HOMO 能级对取代基的性质非常敏感,因此提供了一系列氧化还原电位逐渐变化的有机金属配合物。
