利用两种带相反电荷的卟啉在水溶液中的离子自组装合成卟啉纳米管。离子自组装方法的一个显著优点是改变分子亚基（tectons）以引入所需功能的能力。在卟啉纳米管的情况下，[12]锡卟啉复合物，其在均匀溶液中作为光催化剂，被用作其中一种tecton。纳米管被证明能够光催化还原金属络合物并将金属选择性地沉积到纳米管表面以形成独特的复合纳米结构，[13]从而验证了纳米管中锡卟啉结构的光催化活性被保留。在这项工作中，我们证明了其他合成方法也可以用来产生卟啉纳米结构的离子自组装。具体地，相转移反应用于通过相转移反应生成卟啉双金属束。
synthesis of porphyrin nanotubes using ionic self-assembly of two oppositely charged porphyrins in aqueous solution. A significant advantage of the ionic self-assembly approach is the ability to vary the molecular subunits (tectons) to introduce the desired functionality. In the case of the porphyrin nanotubes, [12] a tin–porphyrin complex, which operates as a photocatalyst in homogenous solution, was used as one of the tectons. The nanotubes were shown to be capable of photocatalytically reducing metal complexes and depositing the metals selectively onto the nanotube surfaces to form unique composite nanostructures, [13] thus verifying that the photocatalytic activity of the tin–porphyrin tectons in the nanotubes is preserved. In this work, we demonstrate that other synthetic approaches can also be used to produce porphyrin nanostructures by ionic self-assembly. Specifically, phase-transfer reactions are used to generate porphyrin nanofiber bundles by the phase
