Stable square planar organocopper(III) complexes (CuNCC2, CuNCC4, and CuBN) supported by carbacorrole-based tetradentate macrocyclic ligands with NNNC coordination cores were synthesized, their structures elucidated spectroscopic means including X-ray crystallographic analysis. On the basis of distinct structures, absorption/photoelectron features, temperature-independent diamagnetic nature, these organocopper can be preferably considered as novel species. The remarkable stability...
Organoplatinum(II) complexes of calix[4]phyrin analogues, singly N-confused (Pt-2), and doubly (Pt-3), were synthesized characterized. The explicit structures these organoplatinum(II) elucidated by single-crystal X-ray diffraction spectroscopic studies. introduction pyrrole rings to the parent scaffold was found have profound effects on photophysical properties, such as bathochromic shifts both absorption phosphorescence maxima. triplet excited state properties platinum analyzed DFT...
Peripheral substitution of a π-extended porphyrin with bulky groups produces curved chromophore four helical stereogenic units. The curvature and stereochemistry such porphyrins can be controlled by varying the substituents, coordinated metal ions, apical ligands. In particular, when achiral saddle-shaped free bases are treated large i.e., Cd
Novel near-infrared phosphorescent iridium(III) complexes based on benzo-annulated N-linked corrole analogue (termed as benzonorrole) were synthesized. The structures of the revealed octahedral coordination geometries involving an organometallic iridium–carbon bond with two external axial ligands. Interestingly, complex exhibits phosphorescence at room temperature wavelengths beyond 900 nm. significant redshift emission, compared to congener, is originated from ligand-centered triplet...
Unsymmetrically fused porphyrins containing one or two naphthalimide subunits were prepared in modular syntheses relying on electron-rich and electron-poor pyrrole building blocks. These new chromophores show progressive changes their electron-deficient character, while retaining comparably small optical electrochemical band gaps. The intrinsic curvature extended absorption of these systems make them interest as mono- difunctional components multichromophoric assemblies.
Free base, zinc and palladium π-extended porphyrins containing fused naphthalenediamide units were employed as photosensitizers in antimicrobial photodynamic therapy (aPDT). Their efficacy, assessed by photophysical vitro photobiological studies on Gram-positive bacteria, was found to depend metal coordination, showing a dramatic enhancement of photosensitizing activity for the complex.
Abstract A family of tunable halochromic switches is developed using a naphthalimide‐fused dipyrrin as the core π ‐conjugated motif. Electronic properties these dipyrrins are tuned by substitution their alpha and meso positions with aryl groups variable donor–acceptor strength. The first protonation results in conformational change that enhances electronic coupling between chromophore substituent, leading to effects occasionally exceed 200 nm switch absorption near‐infrared (NIR)‐I NIR‐II...
Abstract Selective self-assembly of heterodimers consisting two non-identical subunits plays important roles in Nature but is rarely encountered synthetic supramolecular systems. Here we show that photocleavage a donor–acceptor porphyrin complex produces an heterodimeric structure with surprising selectivity. The system forms via multi-step sequence starts oxidative ring opening, which equimolar mixture isomeric degradation products (zinc(II) bilatrien- abc -ones, BTOs). These isomers are...
Abstract Peripheral substitution of a π‐extended porphyrin with bulky groups produces curved chromophore four helical stereogenic units. The curvature and stereochemistry such porphyrins can be controlled by varying the substituents, coordinated metal ions, apical ligands. In particular, when achiral saddle‐shaped free bases are treated large i.e., Cd II or Hg , resulting complexes convert to chiral propeller‐like configurations. X‐ray diffraction analyses show that coordination water...
Abstract A facile synthetic strategy towards conformationally stable chiral chromophores based on dimeric porphyrinoids has been established. peculiar class of face‐to‐face intramolecularly interlocked corrole dimers were formed by the oxidative C−C coupling linked at inner carbon sites upon simple treatment copper(II) ions. Their intrinsic electronic structures modulated peripheral ring annulations, which lead to distinct optical properties and redox profiles. The stereogenic centers...
In order to study the reactivity of various Grignard reagents with differently substituted A 3 ‐ and trans ‐A 2 B‐corrolato Ag III complexes, we have performed a series reactions. We observed that among studied, methylmagnesium chloride is most potent resulted in quantitative demetallation corrolato–Ag complexes produced respective free‐base corroles exclusively. As expected, not formation any unusual σ‐methyl/phenyl derivatives.
