Extending El Sayed's Rule by 1(n,π*)–3(n,π*) Rotation via Intramolecular Secondary Interaction Enables Room‐Temperature Circularly Polarized Phosphorescence in Solution

Angewandte Chemie, EarlyView.
Weak but skilled: Our results highlight the crucial role of intramolecular secondary interactions to induce an efficient ISC between formally identical 1(n,π*) and 3(n,π*) states in chiral thionated phthalimide derivatives. This unprecedented type of inter‐system crossing (ISC) extends the usual thinking of the El‐Sayed principle and enables the ...

Immediate Organic Room‐Temperature Phosphorescence in Programmable Luminescent Tags Enabled by Oxygen‐Free Fabrication

Advanced Materials Technologies, EarlyView.
Programmable luminescent tags based on organic room‐temperature phosphorescence are shown to be governed by oxygen incorporation during fabrication. Oxygen‐free processing enables immediate phosphorescence activation, controlled thermal preconditioning, and tunable activation doses.

An X‑Shaped Chiral Non‑Fullerene n‐Type Semiconductor: Application in Perovskite Solar Cells and Chirality‑Induced Spin Selectivity

Angewandte Chemie, EarlyView.
A highly electron‑accepting derivative of cyclobisbiphenylenecarbonyl (CBBC‐TIC) is reported. CBBC‐TIC functions as an electron‐transport layer for perovskite solar cells, achieving a power conversion efficiency of 20.6%. Furthermore, the enantiomers of CBBC‐TIC exhibited spin‐selective electron transport with high enantiospecific magnetic conductance ...

Evidence that microsomal triglyceride transfer protein is limiting in the production of apolipoprotein B-containing lipoproteins in hepatic cells

Journal of Lipid Research, 1998
The microsomal triglyceride transfer protein (MTP) is a heterodimeric lipid transfer protein that is required for the assembly and secretion of apolipoprotein B (apoB)-containing lipoproteins. A key unresolved question is whether the MTP-mediated step is

Continuous‐Flow Microfluidic Synthesis Enhances C2+ Selectivity for Cu2O Catalysts

Advanced Science, EarlyView.
Microfluidic devices are used to prepare Cu2O nanoparticles under laminar flow conditions, which exhibit enhanced selectivity in the CO2‐to‐C2+ reaction due to their nanoporosity and high defect concentration. Cu2O prepared using standard solution methods displays decreased CO2‐to‐C2+ selectivity due to the absence of similar properties. Altogether, we

CHARACTERIZATION AND ANTIPARASITIC ACTIVITY OF BENZOPHENONE THIOSEMICARBAZONES ON Trypanosoma brucei brucei

Scientific Study & Research: Chemistry & Chemical Engineering, Biotechnology, Food Industry, 2011
The structure of four synthesized thiosemicarbazones, substituted or not, of benzophenone has been confirmed by spectrometrical analysis IR, NMR 1H and 13C. Their anti-trypanosomal activities were evaluated on Trypanosoma brucei brucei.

Safety of benzophenone to be used as flavouring [PDF]

EFSA Journal, 2017
Benzophenone [FL-no: 07.032] has been evaluated as a flavouring substance, in FGE.69, by the EFSA Panel on Food Additives, Flavourings, Processing Aids and Materials in Contact with Food in 2008. Benzophenone was evaluated also by JECFA (2011) and by IARC (2013) based on studies that were not considered in the EFSA opinion on FGE.69.
