摘要

Meso tetra-anthracenyl porphyrin (TAP) was synthesized by pyrrole and 9-anthraldehyde (9-anthracene carboxaldehyde) in different yields. In the current synthetic methods, meso tetra-anthracenyl porphyrin (TAP) was synthesized with 8% yields. The first method involved iodine (I2) as Lewis acid, and in the second method, hydroxyl ammonium chloride (NH2OH·HCl) was used as a Lewis acid and proceeded in the presence of nitrobenzene. The formation of the product was confirmed with the help of various characterizations i.e., UV-visible, 1H NMR, 13C NMR and mass spectrometry.

Graphical abstract

The 5,10,15,20-tetra(9-anthracenyl) porphyrin (TAP) was synthesized by two newer methods in high yield (8% yield). The first method involved iodine (I2) as a catalyst which proceeded at room temperature, and in the second method, hydroxyl ammonium chloride (NH2OH·HCl) was used as a Lewis acid and proceeded in the presence of nitrobenzene. The various UV-vis studies of TAP were studies with different salts and acids.
