➢ 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.
