Sustainable Synthesis of 4,7‐Dihydro‐4,7‐ethano‐2H‐isoindoles—Key Building Blocks to Benzoporphyrins

Chemistry – A European Journal, EarlyView.
A facile and sustainable route to isoindole derivatives—key benzoporphyrin precursors—brings high‐ and low‐symmetry benzoporphyrins closer to practical application. ABSTRACT Benzoporphyrins, π extended porphyrin analogues, exhibit remarkable potential for optoelectronic and theragnostic applications, yet have remained largely confined to fundamental ...

Phosphorescent Iridium Hydrazinonicotinic Acid (HYNIC) Complexes That Bind to Prostate Specific Membrane Antigen: Potential Photodynamic Therapy of Prostate Cancer

Chemistry – A European Journal, EarlyView.
A phosphorescent iridium(III) complex has been prepared with a 6‐hydrazinonicotinic acid (HYNIC) ligand tethered to a lysine‐ureido‐glutamatic acid pharmacophore, which binds to an enzyme, called prostate‐specific membrane antigen (PSMA), which is overexpressed in prostate cancer.

Synthesis and Functional Properties of Fluorinated Phosphonate‐Substituted Porphyrins: Excellent Photosensitizers and Robust Precursors for Photoactive Langmuir–Schaefer Films

Chemistry – A European Journal, EarlyView.
This is a comprehensive study of new family of high functionalized meso‐tetraarylporphyrins. A synthetic approach to phosphonate‐substituted fluorinated porphyrins was developed. These compounds were investigated with respect to singlet oxygen generation and photostability.

Visible‐Light Driven Acetylene Semi‐Hydrogenation to Ethylene With a Copper Photosensitizer and a Cobaloxime Catalyst

Chemistry – A European Journal, EarlyView.
A fully noble‐metal‐free photocatalytic system that couples cobaloxime catalysis with Cu photosensitizer for HAT‐driven acetylene‐to‐ethylene conversion is reported. ABSTRACT The purification of ethylene streams from acetylene impurities remains a key industrial challenge, for which light‐powered strategies are emerging as sustainable alternatives to ...

Covalent Insertion of a Mn(Salen) Type Complex in Cross‐Linked Protein Crystals: Design of an Enantioselective Artificial Epoxidase

Chemistry – A European Journal, EarlyView.
An Artificial metalloenzyme was designed by a Michael addition between a MnSalen complex and a cysteine residue within NikA crystals. The heterogeneous catalyst was found capable of an enantioselective and stereospecific epoxidation of cis‐β‐methylstyrene in cristallo.

Rationales for the Choice of Metals for Super‐Reduced Biological Metal Centers: Cobalt in Cobalamin Versus Nickel in F430

Chemistry – A European Journal, EarlyView.
DFT calculations on porphyrin, corrin, and corphin complexes of cobalt, rhodium, iron, manganese, or nickel, and QM/MM calculations on enzyme models, explore the factors controlling the availably of super‐reduced metal(I) states. True metal(I) states are seen in corrin only for cobalt, in corphin only for nickel, and not at all in porphyrin.

Heteroatom‐Doped Graphdiynes and Their Applications in Photo‐/Electro‐Catalytic CO2 Conversion

Carbon Innovation, EarlyView.
This review highlights the versatile role of doped graphdiyne (GDY) in boosting CO2 conversion, where metal and non‐metal doping simultaneously tune the electronic structure, create abundant active sites, and improve charge separation, light harvesting, and CO2 adsorption.
