Dual‐State Photophysical Modulation via Bifurcated Hydrogen Bonding in a U‐Shaped Dipyridophenazine‐Cored Donor‐π‐Acceptor‐π‐Donor Fluorophore

Chemistry – A European Journal, EarlyView.
A donor–π–acceptor–π–donor (D–π–A–π–D) fluorophore bearing a U‐shaped dipyridophenazine core forms bifurcated hydrogen bonds with neutral donors such as sulfonamides or water. This interaction modulates both ground and excited states, enabling red‐shifted emission and enhanced photoluminescence in solution and solid state.

Modulating the Optoelectronic Properties of Tripodal Fluorophores Through Fluorine‐Substituted Peripheral Phenyls

Chemistry – A European Journal, EarlyView.
C3‐symmetric D‐(π‐D‐π‐A)3 fluorophores featuring central triphenylamine donor, polarizable 2,5‐divinylthiophene linker, and a broad portfolio of fluorine‐based substituents show tunable (non)linear optical properties. ABSTRACT Fourteen novel tripodal fluorophores based on a central triphenylamine donor, electron‐rich, and polarizable divinylthiophene ...

Investigation of microalgal tolerance and growth in simulated tailings pond water containing naphthenic acids

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Oil sands tailings ponds, such as those in northeastern Alberta, present environmental challenges due to slow sedimentation, water entrapment, and toxic naphthenic acids (NAs), which hinder water reclamation. This study assessed the tolerance and biodegradation potential of Chlorella vulgaris (C.

A Facile Protocol for C(sp2)–C(sp3) Bond Formation Reactions Toward Functionalized E3 Ligase Ligands

ChemMedChem, EarlyView.
A robust C(sp2)–C(sp3) decarboxylative coupling strategy enables access to new CRBN ligands and degraders with improved physicochemical properties. This synthetic approach is expanding the chemical space beyond C(sp2)–N linkages, fine‐tuning proteolysis‐targeting chimera activities and unlocking previously inaccessible degrader chemotypes.

Xylose Acetals ‐ a New Class of Sustainable Solvents and Their Application in Enzymatic Polycondensation

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
Novel organic solvents with an unmodified carbohydrate core were synthesised both from D‐xylose and directly from biomass and were successfully used as reaction media for lipase biocatalysts to synthesise aliphatic and aromatic polyesters. Abstract The use of organic solvents in academic research and industry applications is facing increasing ...
