meso-Tetrakis(4′-diethoxyphosphorylphenyl)porphyrin (H2TPhPP) was synthesized via modified Lindsey method with higher yield (50%) as compared to reported methods. H2TPhPP exhibited 120–140 mV anodic shifts in first ring redox potentials as compared to H2TPP. Similarly, anodic shifts of MTPhPP (M = Ni(II), Cu(II), and Zn(II)) were 70–210 mV in first ring oxidation potentials and 80–120 mV in first ring reduction potentials, as compared to corresponding MTPPs due to the strong electron-withdrawing nature of diethoxyphosphoryl substituents.

卟啉(H2TPhPP)采用改进的林登法合成,产率高达50%,相比于已报道的方法更高。与H2
TPP相比,H2TPhPP在第一个环的氧化还原电位上表现出120–140 mV的阳极位移。类似地,
MTPhPP(M = Ni(II)、Cu(II) 和 Zn(II))在第一个环的氧化电位上阳极位移为70–210 mV,在第一个环的还原电位上阳极位移为80–120 mV,这主要归因于二乙氧基
磷酸酯取代基强烈的电子吸引特性。
