A molecular tetrad (C-P-QA-QB) consisting of a carotenoid polyene, a porphyrin and a diquinone moiety has been synthesized. The quinone with the lower reduction potential, the naphthoquinone (QA), was linked directly to the porphyrin and the benzoquinone (QB) was attached in series by a rigid bicyclic bridge. This arrangement was designed to promote a biomimetic sequential electron transfer from the
已经合成了由类胡萝卜素多烯,卟啉和二醌部分组成的分子四分子(CPQ A -Q B)。还原电位较低的醌,萘醌(Q A)直接与卟啉连接,苯醌(Q B)通过刚性双环桥串联连接。这种安排的目的是要促进从卟啉至Q仿生顺序电子转移甲,并在至Q乙。
