porphin การใช้

• The chemical formula of porphin is C 20 H 14 N 4.
• Compounds similar to porphin are the parent compounds for similar ring systems with other central metal atoms in biochemistry.
• Unlike porphin, the central aromatic ring structure of porphyrins, a chlorin is therefore largely aromatic but not aromatic through the entire circumference of the ring.
• "' Porphin "', sometimes spelled "'porphine "', is the parent chemical compound for types of biochemically significant compounds called porphyrins.
• Plasmons can be excited by optical radiation and induce an electric current from hot electrons in materials fabricated from gold particles and light-sensitive molecules of porphin, of precise sizes and specific patterns.
• Porphin is an organic compound that is aromatic and heterocyclic since its chemical structure, shown at right, essentially consists of four pyrrole rings joined together by four methine ( = groups to form a larger macrocycle ring.
