porfyrinibased
Porphyrin-based compounds are a class of heterocyclic macrocycles characterized by four pyrrole subunits linked via methine bridges to form an 18‑electron aromatic system. The core porphyrin ring can coordinate a central metal ion, giving rise to metalloporphyrins such as heme, chlorophyll, and metal phthalocyanines. Substituents on the ring periphery allow fine‑tuning of electronic, steric, and solubility properties, enabling diverse functionalization strategies.
In natural systems, porphyrin-based molecules play critical roles in oxygen transport (heme), photosynthesis (chlorophyll), and catalysis
Porphyrin-based materials are also central to photodynamic therapy (PDT). Upon irradiation, these photosensitizers generate reactive oxygen
Beyond medicine, porphyrin-based nanostructures serve as sensors for gases, toxins, and biomolecules due to their selective
Research continues to expand the scope of porphyrin-based chemistry, exploring novel metal centers, aggregation modes, and
