Abstract Alkylation of one the inner‐core nitrogen atoms is possible approach to obtain dianionic corrole ligands, suitable for coordination divalent metal ions, such as Pd II . Inner‐core N‐methylation can be obtained by treating with CH 3 I, but reaction conditions should optimized limit formation dimethylated derivative. Two regioisomers, N‐21 and N‐22 methyl derivatives are from reaction, first product achieved in a higher amount. Structural characterization products evidenced distortion induced introduction groups; N ‐methylcorroles chiral compounds, enantiomers were separated chromatography, their absolute configuration assigned ECD computation. Palladium insertion was case monosubstituted corroles, not macrocycle; X‐ray complexes showed macrocycles. The do show luminescence emission, able produce singlet oxygen upon irradiation. also inserted human serum albumin (HSA) dispersed water; this case, protein protects corroles photobleaching, switch type I mechanism reactive species (ROS) production observed.

The renaissance in corrole chemistry is strongly correlated with synthetic breakthroughs that started 1999, regarding the one-pot rather than multistep syntheses of this heme-like N4 macrocycle. This largely improved accessibility allowed for technological advances wherein corresponding metal complexes have since been introduced as key elements. Great emphasis was devoted to elucidation unique fundamental features distinguish ligands, among them outstanding electron donation (σ by N atoms and π macrocycle) transition metals chelated them. Such investigations remain crucial enabling by-demand tuning metallocorrole properties distinctly different applications. These range from catalysis organic reactions, through bioimaging disease prevention/treatment strategies, photo- electrocatalysis clean energy. Surveyed are original reports impacted these developments, together some most recent advances.

Two new meso-substituted oxido-molybdenum corroles were synthesized and characterized by various spectroscopic techniques. In the thermogram, MoO[TTC] (1) exhibited excellent thermal stability up to 491 °C while MoO[TNPC] (2) good 318 °C. The oxidation states of molybdenum(V) verified electron paramagnetic resonance (EPR) spectroscopy an axial compression with dxy1 configuration. Oxido-molybdenum(V) complexes utilized for selective epoxidation olefins high TOF values (2066-3287 h-1) in yields a CH3CN/H2O (3:2, v/v) mixture presence hydrogen peroxide as green oxidant NaHCO3 promoter. oxidative bromination catalytic activity oxido-molybdenum(V) aqueous medium has been reported first time. Surprisingly, biomimics vanadium bromoperoxidase (VBPO) enzyme remarkably (36 988-61 646 p-cresol other phenol derivatives. Catalyst higher better than catalyst due electron-withdrawing nitro groups evident from cyclic voltammetric studies.

Abstract The intrinsic quantum nature of molecules opens exciting opportunities for developing the field information science. In this context, porphyrins stand out as ideal building blocks technologies thanks to their unique optical and electrical properties well capacity accommodate metal atoms ions. This review bridges chemistry physics porphyrins, providing an overview recent advances in porphyrin‐based molecular qubits. Starting from qubits, explores potential porphyrin units combine, leading formation logic gates hierarchical higher‐dimensional structures. Next, exploitation porphyrins' photophysical realizing long‐lived high spin states is examined. These are promising photogeneration multi‐level systems initialization control With a critical eye on current state‐of‐the‐art, elucidates future perspectives advancing technologies.

Copper and silver tritolylcorroles (TTC) are symmetrically functionalized to carry two tetracyanobutadiene (TCBD) entities via [2+2] cycloaddition-retroeletrocyclization reaction involving ethynyl corroles with an electron acceptor, tetracyanoethylene (TCNE) in excellent yields, as the first examples of corrole-TCBD push-pull systems. The strong effect resulted charge polarization ground state resulting a considerable hypsochromic shift spectrum extending it into near-IR region. Electrochemical studies coupled computational revealed interactions between TCBD corrole π-system degree such was found depend on metal ion present cavity. Energy considerations suggested transfer (CT) from S2 or vibrationally hot S1 but not relaxed case CuTTC(TCBD)2 while CT occur all these states AgTTC(TCBD)2 . Additionally, high-energy populate low-lying triplet states. Systematic femtosecond pump-probe provided ultimate proof for occurrence excited function excitation wavelength followed by efficient population study brings out significance efficiently populating rather unusual copper carrying entities.

A new family of β-dicyanovinyl (DCV)-appended corroles represented as MTPC(MN) (where M = 3H, Cu, Ag, and Co(PPh3) MN malononitrile TPC 5,10,15-triphenylcorrole) were synthesized starting from the free base mono β-formyl corrole, H3TPC(CHO), characterized along with their respective MTPC(CHO) MTPC complexes to spectroscopic electrochemical properties in nonaqueous media. Comparisons between two series demonstrate a pronounced substituent effect β-DCV group on physicochemical making derivatives substantially easier reduce more difficult oxidize than formyl or unsubstituted corroles. In addition, colorimetric spectral detection 11 different anions (X) form tetrabutylammonium salts (TBAX, X PF6-, OAc-, H2PO4-, CN-, HSO4-, NO3-, ClO4-, F-, Cl-, Br-, I-) also investigated Of anions, only CN- was found induce changes UV-vis 1H NMR spectra metallocorroles. This data revealed that CuTPC(MN) AgTPC(MN) act chemodosimeters for selective cyanide ion via nucleophilic attack at vinylic carbon DCV substituent, while (PPh3)CoTPC(MN) acts chemosensor sensing axial coordination cobalt metal center. low-limit ions observed 1.69 ppm 1.17 toluene.
