Document from the year 2020 in the subject Chemistry - Macromolecular Chemistry, Polymer Chemistry, grade: 2, language: English, abstract: This work gives an overview over core modified Porphyrinoids. Specifically: Smaragdyrins, Expanded Porphyrinoids and Corroles. It does so by, in two chapters, defining each of the aforementioned chemical combinations synthesis and characterization, properties and respective dyads. Smaragdyrin is a pentapyrrolic 22π-electron expanded porphyrin system bearing two direct pyrrole-pyrrole bonds. This macrocycle and its core modified derivative i.e. 25-oxasmaragdyrin have received upsurge interest in recent years due to their notable optical and electrochemical properties. Corroles are aromatic tetrapyrrolic macrocycles containing one meso carbon less compared to porphyrins and have one direct pyrrole-pyrrole linkage. This class of macrocycle possesses novel spectral, electrochemical and luminescence properties that can be exploited in material applications. In this book, we have discussed the synthesis, properties and their limited coordination chemistry of expanded porphyrinoid 25-oxasmaragdyrin and core-modified corroles. Corroles, on the other hand, are tetrapyrrolic contracted porphyrins, fully conjugated 18π electron macrocyles containing three methine bridges and one direct pyrrole-pyrrole linkage.
