Porphyrin has a colorful structure by altering the position of these rings, porphyrin derivatives can be formed, and metals can be included in complex structures. The analysis of porphyrin is conducted under three main headings volta metric analysis, spectro photometric analysis, and HPLC analysis. Chlorines and bacterioclorines, n-substituted por-phytes, aza porphytes, ftalocyanins, and purpurines are analogs of porphyrins. The production of porphyrin varies based on synthesis methods. These differences arise from aldehydes and ketones, and dipiromethan A2BC tetra-substituted por-phyrin, trans-substituted porphyrin synthesis, and symmetrical meso-substituted synthesis methods have been discussed.</dc:description><dc:publisher>wiley</dc:publisher><dc:date>2025</dc:date><dc:type>Book Chapter</dc:type><dc:identifier>https://rdlopen.rawdatalibrary.net/r/kostu/10575</dc:identifier><dc:identifier>https://doi.org/10.1002/9781394214440.ch3</dc:identifier><dc:identifier>978-139421444-0</dc:identifier><dc:identifier>978-139421438-9</dc:identifier><dc:language>en</dc:language><dc:relation>Porphyrin-Based Composites: Materials and Applications</dc:relation><dc:rights>info:eu-repo/semantics/closedAccess</dc:rights><dc:type>info:eu-repo/semantics/bookPart</dc:type><dc:identifier>https://kostu-rdlopen.rawdatalibrary.net/tr/items/kostu/10575</dc:identifier></oai_dc:dc></metadata></record></GetRecord></OAI-PMH>
