Ambiphilic Ligand Stabilization of Aluminum(I) Fragments: Halides, Cations, and a Hydride

Angewandte Chemie, EarlyView.
Stabilization of elusive aluminum(I) halides in the framework of an ambiphilic ligand is reported. The unique bonding situation at the trigonal‐bipyramidal aluminum center is analyzed, and the coordination chemistry and Al(I)Br transfer reactivity of the complexes are presented.

One Molecular Platform, Three Distinct Narrowband Organoboron TADF Emitters: A Divergent One‐Pot Strategy From Green to Red

Angewandte Chemie, EarlyView.
One platform–three emitters: Divergent one‐pot borylation of a single indolocarbazole platform exploits competing mono‐ and double‐borylation pathways to generate three spectrally distinct organoboron MR‐TADF emitters spanning green to red, enabling color‐tunable narrowband OLEDs with external quantum efficiencies over 30%.

Beyond the Oxo‐Wall: Synthesis and Reactivity of a Six‐Coordinate Formally CoIV‐Oxo Complex

Angewandte Chemie, EarlyView.
We present the first example of a six‐coordinate formally Co(IV)‐oxo complex, [Co(TQA)(O)(OH)]+ (1), which exists as an admixture of CoIV‐oxo and CoIII‐oxyl resonance structures. Complex 1 is capable of performing oxygen atom transfer reactions and abstracting moderately strong hydrogen atoms at rates faster than other characterized CoIV‐oxo compounds.

Electronic structures and spectra of conducting anthracene derivatives [PDF]

Journal of the Serbian Chemical Society, 2008
Theoretical studies on anthracene and a series of its derivatives were performed using the AM1 method and DFT. Based on B3LYP/6-31G(d) optimized geometries, the electronic, IR and NMR spectra of anthracene oligomers were calculated using the Indo/Cis ...
