Description

Benzenethiol,4,4',4'',4'''-(21H,23H-Porphine-5,10,15,20-Tetrayl)Tetrakis- is a specialized porphyrin derivative functionalized with benzenethiol groups, representing a high-value advanced chemical intermediate. This compound is critical for applications requiring precise molecular architecture and specific electronic or photophysical properties. It is primarily utilized by research institutions and industrial R&D departments focused on advanced materials science, catalysis, and photodynamic therapy research.

Application

• Advanced Materials Research: A key precursor for constructing metal-organic frameworks (MOFs), covalent organic frameworks (COFs), and supramolecular assemblies due to its tetradentate porphyrin core and functional thiol groups.
• Catalysis Development: Serves as a sophisticated ligand for designing novel homogeneous catalysts, particularly for oxidation and C-H activation reactions, where the porphyrin-metal complex is central to activity.
• Photodynamic Therapy (PDT) Agents: Investigated as a potential photosensitizer building block for next-generation cancer treatments, leveraging its light-absorbing porphyrin structure.
• Organic Electronics: Used in the development of organic semiconductors, dye-sensitized solar cells (DSSCs), and molecular wires where extended conjugation and electron transfer are essential.
• Chemical Sensors: Functional component in the design of selective chemosensors for metal ions or gases, utilizing the distinct colorimetric or fluorescent response of the porphyrin ring upon binding.
• Surface Modification & Self-Assembled Monolayers (SAMs): The peripheral thiol groups enable covalent attachment to gold and other metal surfaces, useful for creating functionalized interfaces in nanotechnology.
