Fluorescence Properties and Mg2+ Selectivity of Aryl‐Alkynyl Derivatives of the o‐Aminophenoltriacetate (APTRA) Ligand

Chemistry – A European Journal, Volume 32, Issue 10, 9 March 2026.
It is a challenge to improve the selectivity of high‐denticity ligands for Mg2+ over Ca2+. We show that in aryl‐alkynyl derivatives of APTRA, electron‐withdrawing substituents lower the binding affinity for Ca2+ more than Mg2+, making the ligand more selective for Mg2+.

Synthesis, Properties, Applications and Challenges of Multicomponent Doped Organic Room Temperature Phosphorescence Materials

Aggregate, Volume 7, Issue 3, March 2026.
The multi‐component doping strategy, involving self‐assembly, host‐guest systems, and crystal engineering, has gained attention for its simplicity, cost‐effectiveness, structural diversity, and adjustable room‐temperature phosphorescence (RTP). This review summarizes and evaluates the progress in creating RTP materials using this strategy, highlighting

Cu‐Catalyzed Tetrafluoroethylation of Aryl Iodides Using “Safe Supply” Tetrafluoroethylene

ChemCatChem, Volume 18, Issue 6, 27 March 2026.
Reaction of [CuH(PPh3)]6 with PMePh2 and readily obtained 1:1 CO2: tetrafluoroethylene affords Cu complex 1 that ffects the CuCl(NHC)‐catalysed tetrafluoroethylation of aryl iodides. ABSTRACT The success of Cu‐mediated, late‐stage fluoroalkylation, originally developed for CF3 transfer, has expanded to additional RF groups including C2F5, CF2H, OCF3 ...

UV photodissociation dynamics of iodobenzene: Effects of fluorination

The Journal of Chemical Physics, 2012
The UV photochemistry of various fluorinated iodobenzenes (4-fluoro-, 2,4-difluoro-, 3,5-difluoro-, and perfluoro-iodobenzene) has been investigated at many wavelengths by velocity map imaging, time-resolved near infrared absorption spectroscopy and (spin-orbit resolved) ab initio calculations of the ground and excited state potentials along the C–I ...

5-Bromo-1,3-dichloro-2-iodobenzene

Acta Crystallographica Section E Structure Reports Online, 2004
The title compound, C6H2BrCl2I, crystallizes in space group P21/c with two mol­ecules in the asymmetric unit. The mol­ecules stack in two different directions, with their plane normals approximately parallel to [110] and [1\overline 10]. The mol­ecules of the asymmetric unit are held together by π–π interactions.
