摘要：Porphyrins and their derivatives are a class of naturally occurring macrocyclic compounds with intense colour, that have been extensively studied due to the key role played in some life processes and involving their special aromatic structure (18πelectrons). Suitable examples that can be given as for oxygen transport (haem), electron transport (cytochrome c) and, most fundamentally, photosynthesis (chlorophyll a). Indeed, without the chlorophylls and bilins (e.g. phycocyanin which acts as a light harvester in algae) life as we know it would not exist on this planet. These are the reasons why porphyrin-derived pigments are called ―the Pigments of Life‖.
