BNB/NBN‐Phenalenyl‐2'‐deoxyuridines as a Fluorophore–Quencher Pair in DNA

open access: yesAngewandte Chemie, EarlyView.
Two BN‐chromophore‐extended nucleosides containing electronically complementary BNB‐ and NBN‐doped phenalenyls were synthesised and incorporated into deoxyribonucleic acid (DNA) oligonucleotides. These chromophores act as an efficient fluorophore–quencher pair under aqueous conditions.

Two‐Dimensional Infrared Spectroscopy Reveals the Presence of a Bridging CO Ligand in Two Catalytic Intermediates of [FeFe] Hydrogenase

open access: yesAngewandte Chemie, EarlyView.
Two‐dimensional (2D) infrared (IR) spectroscopy provides vastly more structural and functional insight into chemical and biological systems than linear IR spectroscopy. Here, we apply 2D‐IR spectroscopy to two controversially discussed states of the [FeFe] hydrogenase active site, revealing the presence of a bridging carbonyl ligand, which is difficult

A Negatively Curved Pyrene‐Fused Azaacene

open access: yesAngewandte Chemie, EarlyView.
A pyrene‐fused azaacene derivative is reported in which steric overcrowding caused by eight phenyl substituents induces bending of the aromatic framework rather than twisting. ABSTRACT Non‐planar aromatic hydrocarbons display distorted π‐frameworks that give rise to unique optoelectronic properties.

Programming Palladium Cage Geometry through Ligand Redox Modulation

open access: yesAngewandte Chemie, EarlyView.
A neutral redox‐active exTTF ligand (L) forms a Pd2L4 cage, whereas its oxidized form (Lox) yields a Pd2(Lox)2 macrocycle. Lox further assembles with a dibenzothiophene derivative (L′) into Pd2(Lox)(L′)2 and Pd4(Lox)4(L′)4 architectures. Reduction of Pd2(Lox)2 and Pd2(Lox)(L′)2 restores the parent Pd2L4 cage, enabling redox controlled nuclearity ...
