Description

5,10,15,20-Tetrakis(4-Ethynylphenyl)-21H,23H-Porphine is a highly functionalized porphyrin derivative characterized by its four peripheral ethynylphenyl groups, which serve as versatile handles for further chemical modification and conjugation. This compound matters as a critical building block in advanced materials science, enabling the creation of complex molecular architectures with tailored electronic and optical properties. It is primarily needed by researchers and manufacturers in the fields of organic electronics, photodynamic therapy, and as a precursor for metal-organic frameworks (MOFs) and covalent organic frameworks (COFs).

Application

• Organic Electronic Materials: A key precursor for the synthesis of conductive polymers and small molecules used in organic light-emitting diodes (OLEDs), organic photovoltaics (OPVs), and field-effect transistors (OFETs).
• Photodynamic Therapy (PDT) Agents: Serves as a core scaffold for developing novel photosensitizers due to its porphyrin structure, which can be tuned for specific light absorption and singlet oxygen generation.
• Porous Framework Construction: Utilized as a tetrahedral linker or node in the synthesis of Metal-Organic Frameworks (MOFs) and Covalent Organic Frameworks (COFs) for gas storage, separation, and catalysis.
• Molecular Sensor Development: Functionalized to create highly sensitive and selective chemical sensors for the detection of metal ions or small molecules.
• Surface Modification & Catalysis: The ethynyl groups allow for grafting onto various surfaces (e.g., gold, carbon nanotubes) or attachment to catalytic metal centers, creating heterogeneous catalysts.
• Nonlinear Optical (NLO) Materials: Investigated for use in NLO applications due to the extended π-conjugation system of the porphyrin core combined with the ethynyl linkages.
