卟啉超分子是通过与中心金属离子配位、氢键或与外部金属离子络合等方式构建的。Meso-N-甲基-2-咪唑基取代的卟啉分别通过咪唑基与锌和镁的互补配位模拟了一种特殊的配对模型和捕光天线。吸收光谱中Soret谱带的特征分裂和1H核磁共振谱中咪唑基和吡咯基β质子的较大上场位移表明两个卟啉π-π平面非常接近。2，5-二羟基苯基取代卟啉的配位结构也观察到了~1H核磁共振谱的前场位移。作为氢键组织的一个例子，咪唑取代基之间的超分子组装在溶液中提供了具有天线功能的卟啉堆叠，并导致了稳定的天线脂质体的形成，没有任何脂质成分，如卵磷脂。一元和双(8-羟基-5-喹啉基)取代的卟啉.
Porphyrin supramolecules were constructed by ligand coordination to central metal ions, hydrogen bonding, or chelate complexation to external metal ions. meso-N-Methyl-2-imidazolyl-substituted porphyrin afforded a special pair model and a light-harvesting antenna mimic by complementary coordination of imidazolyl to Zn and Mg, respectively. Characteristic splits of the Soret band in absorption spectra and large upfield shifts of imidazolyl and pyrrolic β protons in the 1H NMR spectra suggested the close proximity of two porphyrin π–π planes. Such upfield shifts in the 1H NMR spectra were also observed for coordination organization of 2,5-dihydroxyphenyl-substituted porphyrinatoMg. As an example of organization by hydrogen bonding, the supramolecular assembly between imidazolyl substituents afforded stacks of porphyrins with antenna function in solution and gave rise to the formation of stable antenna liposome without any lipid components such as lecitin. Mono- and bis(8-hydroxy-5-quinolyl) substituted porp...
