Synthesis of meso-tetrakis (2, 10-dioxo-2H, 10H-pyrano[2,3-f] chromene-9-yl) porphyrins are synthesized directly by reaction of pyrrole with substituted 4-methyl-2,10-dioxo-2H, 10Hpyrano[2,3-f]chromene-9-carbaldehydes in dichloromethane / acid media. The aldehyde’s molar ratio was controlled to optimize the synthesis and purification of the desired porphyrins. This new series of porphyrins was characterized
meso-tetrakis (2, 10-dioxo-2H, 10H-pyrano[2,3-f] chromene-9-yl) 卟啉的合成是通过吡咯与取代的 4-methyl-2,10-dioxo-反应直接合成的二氯甲烷/酸介质中的 2H, 10Hpyrano[2,3-f]chromene-9-carbaldehydes。控制醛的摩尔比以优化所需卟啉的合成和纯化。这个新系列的卟啉通过 TLC、质谱(FAB 质量)、H NMR、UV 和 IR 进行表征
