The metal-free porphyrins protonation has gained interest over five decades because its structure modification and hardly monoacid intermediate isolation. Here, upon the hydrogen atom abstraction processes, one step diproptonated H3STTP(BF4)2 (STTP = 5,10,15,20-tetraphenyl-21-thiaporphyrin) (3) stepwise protonated HS2TTPSbCl6 (5) diprotonated H2S2TTP(BF4)2 (6) (S2TTP 5,10,15,20-tetraphenyl-21,23-thiaporphyrin) compounds were obtained using HSTTP S2TTP with oxidants. closed-shell fully characterized XRD, UV-vis, IR NMR spectra. In addition, reduced 19π [K(2,2,2)]HSTTP (2) [K(2,2,2)]S2TTP (7) synthesized by ligands reductant KC8 in THF solution. These two open-shell EPR spectroscopies. semiempirical ZINDO/S method was employed to analyze HOMO/LUMO gap lever identify electronic transitions of UV-vis spectra closed- porphyrin compounds.
