ABSTRACT
Photochemistry of the porphyrins and their relatives has been largely inspired by photosynthetic processes in nature. As a result of this, most current studies generally utilize the chemistry of magnesium and zinc porphyrin analogues. Especially, magnesium tetrapyrrole chelates, that is, magnesium porphyrins and phthalocyanines, have found wide interest. is is primarily related to the biological relevance of magnesium porphyrins in nature, notably in photosynthesis and electron transfer (ET), and thus, we will focus on this aspect in this review. Outside these areas, not many “true” photochemical studies have been performed with magnesium tetrapyrroles.
