The Unique Structure–Activity Relationship of Porphyrins and Clay Mineral Systems in Modern Applications: A Comprehensive Review [PDF]

Chemical and Biochemical Engineering Quarterly
Porphyrins are a group of organic heterocyclic macromolecules, composed of four modified pyrrole subunits interconnected at their α carbon atoms via methine bridges. This unique and significant group of compounds has a special relationship with inorganic

Encapsulation of Porphyrins in Polymer Microgels and Microbeads for Heterogeneous Photooxidation

ChemSusChem, Volume 19, Issue 19, 14 October 2026.
Amino‐ or ammonium‐functionalized tetraphenylporphyrins were synthesized and encapsulated within polymers to form microgels and microbeads that act as heterogeneous photocatalysts. Photooxidation in aqueous media quantitatively converts sulfides and aldehydes into sulfoxides and carboxylic acids via the singlet‐oxygen pathway, demonstrating an ...
