➢ Tetraphenylporphyrin (TPP) as an important class of
conjugated macrocyclic compounds, contain methine bridges
(=CH–) and plays an important role in essential for life.
➢ The compound is a dark purple solid that dissolves in
non-polar organic solvents such as chloroform and
benzene.➢ Porphyrin has a delocalized system involving 26 π electrons and satisfies
Huckel’s rule for aromaticity (4n + 2p electrons).
➢ The π electrons of porphyrin lead to their unique optical,
electronic, magnetic, redox, catalytic, Self-assembly, and other
properties.
➢ These excellent physicochemical properties of porphyrin
used for fabrication of sensing and electro catalyst nano
architecture.
