meso-Functionalized [5-triisopropylsilylethynyl-10,20-bis(heptafluoropropyl)porphinato]zinc(II) and [5-iodo-10,20-bis(heptafluoropropyl)porphinato]zinc(II) building blocks lay the foundation for the construction of highly conjugated multiporphyrin arrays that feature electronic structural properties important for the development of n-type materials and high potential photooxidants.
描述了带有不同官能团的缺电子内消旋全氟烷基卟啉的合成策略。5-三异丙基甲硅烷基乙炔基-10,15,20-三(七氟丙基)卟啉和 5-三异丙基甲硅烷基乙炔基-10,20-双(七氟丙基)卟啉的可扩展高效合成,通过已经建立了双烷路线,以及 [5,15-双(七氟丙基)卟啉基]锌(II)的精制路线。[5,15-双(七氟丙基)卟啉基]锌(II)的中间位卤化是通过选择性硝化和随后的还原、重氮盐形成和碘化反应实现的。计算数据描述了这些发色团的低能激发态和控制这些内消旋-全氟烷基取代卟啉配合物反应性的电子结构因素。meso-Functionalized [5-triisopropylsilylethynyl-10,20-bis(heptafluorpropyl)porphinato]zinc(II) and [5-iodo-10,
