چکیده:

Porphyrin, is one of the most important issues in natural and biologic investigations and it has been studied for many years [1,2]. Porphyrin molecules are useful building blocks for manufacturing molecular wires [3].Aromatic molecules have p-conjugation systems through which electrons can flow easily. By substituting different functional groups on an aromatic system it is possible to increase or decrease the p-electron density [4]. Porphyrin structure is considerable to form a conducting channel in compressed arrangement of p-p orbitals
