Co(II)-porphyrin complexes with nitrogen monoxide and imidazole: synthesis, optimized structures, electrochemical behavior and photochemical stability

Phosphonate-substituted porphyrins as efficient, cost-effective and reusable photocatalysts

“…73,74 In the case of Co(TPPP), the position of the Soret band was close to those observed for other Co(II) complexes with 5,10,15,20-tetraarylporphyrins bearing electron-deficient substituents. 75 As expected, the absorption maxima of Pd(TPPP) appeared blue-shifted compared to those of Zn(TPPP). 67 This blue shift was accompanied by a decrease in the extinction coefficient coming along with an increase in the full-width-athalf-maximum of the Soret band, as previously observed for Pd(II) porphyrin complexes.…”

Aromatic heterobicycle-fused porphyrins: impact on aromaticity and excited state electron transfer leading to long-lived charge separation

“…56,57 Benzimidazole is also known as a ligand to metals. [58][59][60] However, the impact of benzimidazole moiety on aromaticity and electronic structures of p-extended structures remains elusive. Benzo [4,5]imidazo[2,1-a]isoindole induces intrinsic dipole moments in the p-extended molecule owing to the presence of the amidine component (Figure 1) and is expected to bring in new functionalities.…”
