卟啉阵列是通过桥接单元或键组装而成的多卟啉体系,其电子性质取决于桥接单元以及卟啉连接的位置。由于电子相互作用的卟啉阵列在光电子器件、传感器、光伏电池、非线性光学材料以及光动力治疗的染料等方面的潜在应用价值,在过去的几十年中,科学家们对其进行了大量探索。卟啉阵列的构筑主要包括非共价组装与共价组装两种方式,前者相对容易但构筑的阵列稳定性较差,后者相对较难但构筑的阵列稳定性较好。铃木偶联是指用零价钯催化卤代烃与烃基硼酸或硼酸酯交叉偶联的反应,它是构筑结构多样、性质各异的卟啉阵列的有效手段。本文主要对其近年来在构筑多卟啉阵列方面的研究进展进行综述。最后,展望了铃木偶联构筑卟啉阵列的发展趋势。
Porphyrin arrays are multi-porphyrin systems assembled by bridging units or bonds whose electronic properties depend on the bridging unit and the position of the porphyrin attachment. Due to the potential applications of electron-interactive porphyrin arrays in optoelectronic devices, sensors, photovoltaic cells, non-linear optical materials, and photodynamic therapy dyes, scientists have explored it in the past few decades . Porphyrin arrays mainly include non-covalent assembly and covalent assembly two ways, the former is relatively easy to build the array stability is poor, the latter is relatively difficult to build the array stability is better. Suzuki coupling refers to the reaction catalyzed by zero-valent palladium for the cross-coupling of halogenated hydrocarbons with boronic acids or boronic esters. It is an effective means to construct porphyrin arrays with diverse structures and different properties. In this paper, the recent progress in the construction of multi-porphyrin arrays is reviewed. Finally, the development trend of the porphyrin array constructed by Suzuki coupling is prospected.
