Sepiolite promotes photodegradation of pyrene under visible light
Ecotoxicology and Environmental Safety, 2023 Mechanochemistry and photocatalysis are emergent technologies for the remediation of polycyclic aromatic hydrocarbons (PAHs) in soils. In this work, mechanochemistry and photocatalysis are combined for pyrene degradation.

Fate and distribution of pyrene in Ilyanassa obsoleta exposed through the diet [PDF]
Invertebrate Survival Journal, 2010 The ability of Eastern mud snails to bioaccumulate and biotransform a model polycyclic aromatic hydrocarbon (PAH), pyrene (PY), was investigated. The contaminant was added to fish at levels ranging from 2 to 5,000 ng/animal fed 20 mg/each and fed to ...

Dynamic exciton localisation in a pyrene–BODIPY–pyrene dye conjugate [PDF]
Physical Chemistry Chemical Physics, 2019 The photophysics of a molecular triad consisting of a BODIPY dye and two pyrene chromophores attached in 2-position are investigated by steady state and fs-time resolved transient absorption spectroscopy as well as by field induced surface hopping (FISH) simulations.

(4Z,5E,9E,10Z)-N4,N5,N9,N10-Tetrakis(2,6-diisopropylphenyl)pyrene-4,5,9,10-tetraimine
IUCrData, 2016 The title molecule, C64H74N4, consists of a pyrene backbone with imine moieties located on the 4-, 5-, 9-, and 10-positions of the ring system. The aryl groups on these imines are sterically bulky 2,6-diisopropylphenyl units.

Cell Reports Physical Science, 2022 Summary: Pyrene is known for the quenched emission of excimers, especially in aqueous solution. Here, we report strong emission of pyrene excimers realized in amphiphile assemblies by controlling the face-to-face distance between the pyrene planes.

Acta Crystallographica Section E Structure Reports Online, 2010 The asymmetric unit of the title compound, C(17)H(12)O, contains two molecules, in which the fused aromatic ring systems are almost planar [maximum deviations = 0.0529 (9) and 0.0256 (9) Å]. In the crystal, aromatic π-π stacking inter-actions (perpendicular distance of centroids of about 3.4 Å) and strong O-H⋯O hydrogen bonds result in a helical ...
