21, 23-Dithiaporphyrins and 21-monothiaporphyrins with propane-1, 3-diyldioxy and its derivatives at the β-thiophene carbons were synthesized and characterized. The cyclic substituents introduced at the β-thiophene carbons altered the electronic properties of the porphyrins. The X-ray structure for 2, 3-bis (2, 2-dibenzylpropane-1, 3-diyldioxy) substituted 21-monothiaporphyrin showed a more planar structure compared to the saddle shaped ...
