N-Heterocyclic Carbene-Catalyzed Synthesis of α-Trifluoromethyl Esters

The N-heterocyclic carbene (NHC)-catalyzed trifluoromethylation of α-chloro aldehydes was developed, allowing straightforward access to valuable α-trifluoromethyl ester derivatives. The unique combination of an electrophilic trifluoromethylation…

Fast 3D Microscopy Imaging of Contacts Between Surfaces Using a Fluorescent Liquid

A novel method is presented for the rapid direct 3D visualization of the contact between two surfaces by means of fluorescence microscopy using a fluorescent liquid. Distances between the surfaces of up to several hundred nanometers can be…

A (Triphenylphosphine)Silver (I) Complex as a New Performance Additive in Free-Radical Photopolymerization under Air

Unusual photochemical properties of an Ag(I)-derived complex, i.e., bis[(µ-chloro)bis(triphenylphosphine)silver (I)] ([Ag](PPh3)) are demonstrated when used in free-radical photopolymerization reactions: i) [Ag](PPh3) can act as an innovative…

The unsuspected influence of the pyridyl-triazole ligand isomerism upon the electronic properties of tricarbonyl rhenium complexes: An experimental and theoretical insight

Two isomeric tricarbonyl rhenium(i) complexes, ReL1 and ReL2, that possess a 2-pyridyl-1,2,n-triazole (pyta) ligand (n = 4 and 3, respectively) connected to a 2-phenylbenzoxazole (PBO) moiety, were synthesized in good yields. The X-ray structures…

On the temperature dependence of the quenching by a few defects of TADF materials. Triplet versus Singlet FRET

Thermally Activated Delayed Fluorescence (TADF) molecules contribute to the light emission of an optoelectronic device from both their singlet and triplet states. But the quenching limits these benefits. In the case of cationic (NHC)Cu(I) complexes…
