WebMacrocyclic porphyrin with charged substituents makes it water-soluble entities along with maintaining the hydrophobic character of porphyrins. The self-assembly of porphyrin aggregation in presence of other templates leads to form predefined nano-architectures. Such templates are employed to retain chirality at the supramolecular level. WebPorphyrins are ubiquitous in nature, as a heme cofactor of hemoglobin, cytochromes, and other redox active enzymes, and, as more saturated analogs, in the photosynthetic apparatus in plants and bacteria. Tetrapyrrolic macrocycles have been widely examined for their unique optical and redox properties.
