Modular Nitrogen-Doped Concave Polycyclic Aromatic Hydrocarbons for High-Performance Organic Light-Emitting Diodes with Tunable Emission Mechanisms
Although bowl-shaped N-pyrrolic polycyclic aromatic hydrocarbons (PAHs) can achieve excellent electron-donating ability, their application for optoelectronics is hampered by typically low photoluminescence quantum yields ...
C−H Functionalization of Heterocycles with Triplet Carbenes by means of an Unexpected 1,2-Alkyl Radical Migration
The C−H functionalization of indole heterocycles constitutes a key strategy to leverage the synthesis of endogenous signaling molecules such as tryptamine or tryptophol. Herein, we report on the photocatalytic reaction of ...
Encapsulation in Charged Droplets Generates Distorted Host-Guest Complexes
The ability of various hydrogen-bonded resorcinarene-based capsules to bind α,ω-alkylbisDABCOnium (DnD) guests of different lengths was investigated in solution and in the gas-phase. While no host-guest interactions were ...
Vitamin B12: An efficient cobalt catalyst for sustainable generation of radical species
Vitamins are organic molecules that are essential for the proper functioning of mammalian cells. Among them, there is only one organometallic molecule: vitamin B12, a natural cobalt complex that is involved in DNA synthesis ...
