Sepiolite promotes photodegradation of pyrene under visible light

open access: yesEcotoxicology 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.

Unpredicted Concentration-Dependent Sensory Properties of Pyrene-Containing NBN-Doped Polycyclic Aromatic Hydrocarbons

open access: yesMolecules, 2022
Pyrene molecules containing NBN-doped polycyclic aromatic hydrocarbons (PAHs) have been synthesized by a simple and efficient intermolecular dehydration reaction between 1-pyrenylboronic acid and aromatic diamine.

Pyrene-based aggregation-induced emission luminogens and their applications

open access: yesMaterials Chemistry Frontiers, 2019
Pyrene shows very weak or quenched fluorescence in the solid state, but it is possible to turn it to a bright solid emitter by using aggregation-induced emission (AIE) strategies.

Dynamic exciton localisation in a pyrene–BODIPY–pyrene dye conjugate [PDF]

open access: yesPhysical 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.

Fate and distribution of pyrene in Ilyanassa obsoleta exposed through the diet [PDF]

open access: yesInvertebrate 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 ...

Benzo[a]pyrene activates interleukin-6 induction and suppresses nitric oxide-induced apoptosis in rat vascular smooth muscle cells. [PDF]

open access: yesPLoS ONE, 2017
Benzo[a]pyrene, a ubiquitous environmental pollutant, has been suggested to be capable of initiating and/or accelerating atherosclerosis. Accumulation of vascular smooth muscle cells (VSMCs) in vessel intima is a hallmark of atherosclerosis. Nitric oxide

Li+ Selective Podand-Type Fluoroionophore Based on a Diphenyl Sulfoxide Derivative Bearing Two Pyrene Groups

open access: yesMolecules, 2011
New podand-type fluoroionophores having two pyrene moieties: 2,2´-bis(1-pyrenylacetyloxy)diphenyl sulfide (3), 2,2´-bis(1-pyrenylacetyloxy)diphenyl sulfoxide (4), and 2,2´-bis(1-pyrenylacetyloxy)diphenyl sulfone (5), have been synthesized by connecting ...

Biotreatment of pyrene and Cr(VI) combined water pollution by mixed bacteria

open access: yesScientific Reports, 2021
Pyrene and chromium (Cr(VI)) are persistent pollutants and cause serious environmental problems because they are toxic to organisms and difficult to remediate.

Influence of perylenediimide–pyrene supramolecular interactions on the stability of DNA-based hybrids: Importance of electrostatic complementarity

open access: yesBeilstein Journal of Organic Chemistry, 2014
Aromatic π–π stacking interactions are ubiquitous in nature, medicinal chemistry and materials sciences. They play a crucial role in the stacking of nucleobases, thus stabilising the DNA double helix.

Strong emission of excimers realized by dense packing of pyrenes in tailored bola-amphiphile nano assemblies

open access: yesCell 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.
