Data on quantification of PAHs and elemental content in dry Camellia sinensis and herbal tea

Data in Brief, 2018
Here we present data on potentially toxic metals and polycyclic aromatic hydrocarbons (PAHs) in commercially sold tea brands in Nigeria. The article provides data on the sequential extraction and the pseudo-total concentrations of eight metals (Cd, Cr ...

New classes of organic pollutants in the remote continental environment – Chlorinated and brominated polycyclic aromatic hydrocarbons on the Tibetan Plateau

Environment International, 2020
Halogenated polycyclic aromatic hydrocarbons are carcinogenic and ubiquitous environmental organic pollutants. The abundance and sources of these compounds have not been studied in remote environments.

Polycyclic Aromatic Hydrocarbons in Bovine Lens

Ophthalmic Research, 2009
A study was performed to detect the presence of polycyclic aromatic hydrocarbons (PAHs) in bovine eyes. Twenty fresh bovine eyes were used to detect the presence of PAHs in lens, vitreous and aqueous by HPLC and spectrofluorometer. In lenticular tissue the mean amount of PAHs was 0.0271 μg/g and the mean level of PAH in each lens was 0.059 μg.

Recent Advances in Sample Preparation and Chromatographic/Mass Spectrometric Techniques for Detecting Polycyclic Aromatic Hydrocarbons in Edible Oils: 2010 to Present

Foods
Polycyclic aromatic hydrocarbons are considered to be potentially genotoxic and carcinogenic to humans. For non-smoking populations, food is the main source of polycyclic aromatic hydrocarbons exposure.

Peroxide‐Assisted Solvate Engineering Enables Record‐High Birefringence in a Solar‐Blind Transparent Crystal

Angewandte Chemie, EarlyView.
H2O2‐directed solvate engineering reorganizes ∞[4HP] (4‐hydroxypyridine) chains from a crossed arrangement into a nearly parallel packing through strengthened hydrogen‐bonding interactions. The resulting peroxide‐containing crystal, 4HP·H2O2, exhibits a solar‐blind UV cutoff edge (278 nm) and giant birefringence (0.609 @ 546 nm). This work demonstrates

Machine‐Learning‐Guided Discovery of Boron‐Free Narrowband Blue Thermally Activated Delayed Fluorescence Emitters

Angewandte Chemie, EarlyView.
A data‐driven discovery engine—exhaustive enumeration of carbazole‐containing polycyclic aromatic hydrocarbons (Cz‐PAHs) followed by machine learning—identifies boron‐free, narrowband blue thermally activated delayed fluorescence emitters for organic light‐emitting diodes (OLEDs).

3D and 2D aromatic units behave like oil and water in the case of benzocarborane derivatives

Nature Communications, 2022
2D/2D fusion of aromatic halves leading to a global aromatic is found in many polycyclic aromatic hydrocarbons, whereas 2D/3D aromaticity is difficult to achieve. Here the authors report a computational chemistry investigation showing that 3D/2D aromatic

Divergent Synthesis of Möbius and Hückel N‐Heterocycloarenes From a Common Macrocyclic Backbone

Angewandte Chemie, EarlyView.
In the divergent synthesis of Möbius and Hückel N‐heterocycloarenes from a common macrocyclic precursor, the annulation reaction dictates topology: Scholl reaction gives Möbius topology, while InCl3‐mediated alkyne annulation gives Hückel topology. The Möbius N‐heterocycloarene is unevenly contorted as revealed by crystal structure, and the Hückel N ...
