卟啉化合物在模拟光合作用、探索高效利用太阳能等方面具有重要的理论意义和应用前景。近年来,人们对共价键相连的“卟啉-醌”类化合物研究较多,而关于“卟啉-硝基”类化合物的报道则较少,硝基具有强吸电子等特性,它作为“卟啉-硝基”类化合物的电子受体有利于分子内发生电子传递,可望是光合作用机理研究中的一类较好的模型化合物。为此,我们设计合成了具有不同性质的供体和不同位置的受体的8种新硝基苯甲酸及苯甲酸卟啉酯类化合物,它们的结构已分别通过质谱、核磁、红外、紫外可见光谱以及元素分析确证,结果见表1、2。
Porphyrin compounds have important theoretical significance and application prospect in simulating photosynthesis and exploring the efficient use of solar energy. In recent years, there have been many studies on “porphyrin-quinone” compounds linked by covalent bonds, while few reports on “porphyrin-nitro” compounds have been reported. Nitrogens have strong electron-attracting properties. The electron acceptor of “porphyrin-nitro” compounds is conducive to the intramolecular electron transfer and is expected to be a good model compound in the study of photosynthesis mechanism. To this end, we design and synthesize eight new nitrobenzoic acids and porphyrin benzoate compounds with different types of donors and acceptors at different positions. Their structures have been characterized by MS, NMR, IR and UV respectively Spectral and elemental analysis confirmed that the results in Table 1,2.
