Panchromatic and Perturbed Absorption Spectral Features and Multiredox Properties of Dicyanovinyl- and Dicyanobutadienyl-Appended Cobalt Corroles

“…16−18 The HOMO−LUMO gap can easily be decreased by appending the conjugated π-systems with donor−π−acceptor groups. 19,20 Recent studies on conjugated porphyrinoids revealed that porphyrin-based dyes with NIR absorption had demonstrated potential applications in nonlinear optics, 21,22 photodynamic therapy, 23−25 OLEDs, 26 molecular wires, 27 and molecular electronics. 28 Corroles are less explored in the areas of photonics and photocatalysis and have shown promising properties.…”

“…π-Extended porphyrinoid dyes have received notable interest due to unique photophysical, structural, and redox properties that lead to panchromatic absorption in the near–infrared (NIR) region. − Usually, porphyrin dyes have weak absorption in the red region . The absorption spectra of porphyrinoids are quite flexible and can be easily perturbed by varying β- and/or meso -substituents. − Developing fused or conjugated porphyrins is one effective and straightforward methodology for tuning redox and photophysical properties. − The HOMO–LUMO gap can easily be decreased by appending the conjugated π-systems with donor−π–acceptor groups. , Recent studies on conjugated porphyrinoids revealed that porphyrin-based dyes with NIR absorption had demonstrated potential applications in nonlinear optics, , photodynamic therapy, − OLEDs, molecular wires, and molecular electronics …”

Effect of para‐Substituents on meso‐Functionalized Oxidovanadium(IV) Porphyrins as Catalysts for Oxygen Atom Transfer Mediated Oxidation of Benzoin to Benzil under Mild Conditions

“…[21] Recently, the oxidation of deoxy benzoins to the corresponding 1,2-diones by Pd-nanoparticle catalyst and DMSO as an oxidant has been demonstrated. [22] Metalloporphyrins are very useful in chemical sensors, [23] nonlinear optics, [24] quantum information processing, [25] dyesensitized solar cells, [26,27] ultrafast dynamics, [28] therapeutics, [26,27] and catalysis; [29][30][31][32][33][34][35][36] some of them like Cr(IV), [37] Fe(III), [38,39] Co-(II) [40,41] and Mn(IV) [42] are very handy catalysts for OAT reactions because of their tailored spectral features and rich electrochemistry. [43][44][45] However, the catalytic oxidation of benzoin to benzil has never been explored using vanadium porphyrins.…”

Single Pyrrole Unit Functionalized Electron Deficient Porphyrins and Their Metal Complexes: Synthesis, Structural, Spectral and Electrochemical Properties

“…dye-sensitized solar cells (DSSCs) [12][13][14][15][16] and nonlinear optics (NLO). [5,[17][18][19][20] Depending on whether porphyrin is functionalized at the meso-position or the βposition, the optical properties as well as the electrical properties will be impacted differently. [21][22][23][24] A significant portion of the push-pull porphyrins documented in literature exhibit functionalization predominantly at the meso-positions of the porphyrin ring.…”

“…Several researchers have synthesized such donor‐acceptor porphyrins and employed the same in outstanding applications viz . dye‐sensitized solar cells (DSSCs) [12–16] and nonlinear optics (NLO) [5,17–20] . Depending on whether porphyrin is functionalized at the meso‐position or the β ‐position, the optical properties as well as the electrical properties will be impacted differently [21–24] .…”
