Dual room‐temperature phosphorescence derived from the reversible homolysis in the high proportion n‐electron organic crystal

open access: yesSmart Molecules, EarlyView.
[2,2′‐biisoindoline]‐1,1′,3,3′‐tetraone (4A2B) crystal with high n‐electrons undergoes photo‐induced reversible homolysis resulting in two room‐temperature phosphorescence (RTP). One of the 4A2B molecules responds strongly to 250 nm via fast intersystem crossing (ISC) processes among high‐lying excited states.

Hydrogen‐bond‐mediated retention of a phenolic SNAP analogue in polyvinyl alcohol/PEG hydrogels for sustained nitric oxide release and antibacterial activity

open access: yesSmart Molecules, EarlyView.
A hydrogen‐bond‐donating NO donor was designed to interact specifically with the hydrogel network, thereby minimizing donor leakage and achieving prolonged NO release. Abstract Nitric oxide (NO)‐releasing materials have attracted considerable interest for their potential in diverse biomedical applications.

Five Decades of Dispute: A Triptych. E. J. Corey

open access: yesThe Chemical Record, EarlyView.
In his 2004 Priestley Medal address, E. J. Corey stated, “On May 4, 1964, I suggested to my colleague R. B. Woodward a simple explanation involving the symmetry of the perturbed (HOMO) molecular orbitals for the stereoselective cyclobutene/1,3‐butadiene and 1,3,5‐hexatriene/cyclohexadiene conversions that provided the basis for the further development ...

Beyond Removal Efficiency: Environmental Risk Assessment of Tartrazine Degradation via ZnO and TiO2 Nanoparticles in Mussels

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Tartrazine (TZ) is a widely used synthetic azo dye with high aqueous stability, resulting in persistence in wastewater. Photoreactive nanomaterials, principally zinc oxide (ZnO) and titanium dioxide (TiO2) nanoparticles (NPs), are frequently employed for dye removal under light‐exposed conditions; nevertheless, their ecotoxicological ...

Cytogenotoxic and Molecular Assessment of Pyrethrins on Non‐Target Allium cepa Roots

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT The pyrethrins, which form a part of naturally occurring insecticidal chemicals derived from chrysanthemum flowers, not only provide rapid knockdown of a broad spectrum of insect pests but are also widely used in integrated pest management due to a generally favorable safety profile, largely attributed to low mammalian toxicity.

The 5T Paradox of Triclosan: From Toiletries to Toxic Trash, a Growing Threat to Humanity

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Triclosan (TCS) persists as a contaminant of concern in the Anthropocene, despite regulatory actions. Environmental dissemination continues through wastewater effluents, biosolid application, and improper disposal practices. This narrative review synthesizes current evidence regarding triclosan's environmental fate, transformation pathways ...

Photocatalytic and Biotechnological Strategies for Remediation of Persistent Organic Pollutants: Mechanisms, Toxicity, and Antimicrobial Perspectives

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Persistent organic pollutants (POPs) pose significant ecological and human health risks due to their persistence, bioaccumulation, toxicity, and global distribution. Conventional remediation methods are often inadequate for achieving complete mineralization, demonstrating the need for advanced and substantial approaches.
