The present work demonstrates a simple and elegant strategy by which synthetically simple porphyrins are grafted on solid polymer support to generate porphyrin pairs held together by strong coulombic forces. Metalloporphyrins of tetra(4-pyridyl)porphyrins (MTPyP) were reacted with chloromethylated polystyrene (PS) beads to get covalently bound monocationic porphyrins on the polymer support (PS–MTPyP+). These were then converted to their tetracationic species (PS–MTMe3PyP4+) by exhaustive quaternisation, using CH 3 I . These polymer-grafted cationic porphyrins were made to react with tetraanionic p-sulphonated phenylporphyrins (MTPPS4-) in aqueous conditions. Analysis showed that the PS–MTMe3PyP4+ take up MTPPS4- in exactly 1:1 stoichiometry to form strongly bound (ionically) porphyrin pairs. A variety of homo- and hetero-porphyrin pairs involving central metal ions like Mn , Co , Cu , Zn and Ag and also free-base porphyrins are generated by this strategy.

固体聚合物载体上的离子结合金属卟啉对

目前的工作展示了一种简单而优雅的策略，通过该策略将合成简单的卟啉接枝在固体聚合物载体上，以产生通过强库仑力结合在一起的卟啉对。四（4-吡啶基）卟啉（MTPyP）的金属卟啉与氯甲基化聚苯乙烯（PS）珠反应，在聚合物载体（PS-MTPyP）上得到共价结合的单阳离子卟啉+）。然后将它们转化为它们的四阳离子物种（PS-MTMe3焦磷酸4+) 通过详尽的季铵化，使用 CH3一世 。这些聚合物接枝的阳离子卟啉与四阴离子对磺化苯基卟啉（MTPPS4-) 在水性条件下。分析表明，PS-MTMe3焦磷酸4+参加 MTPPS4-在精确的 1:1 化学计量中形成强结合（离子）的卟啉对。这种策略产生了多种同型和异型卟啉对，包括中心金属离子如 Mn、Co、Cu、Zn 和 Ag，以及游离碱卟啉。
