BODIPY‐based J‐aggregates: From supramolecular chemistry to NIR bioimaging and phototherapies

Bulletin of the Korean Chemical Society, EarlyView.
BODIPY dyes form ordered J‐aggregates through controlled supramolecular self‐assembly, producing narrow, red‐shifted absorption bands with small Stokes shifts. This review highlights design strategies governing J‐aggregation, structure–property relationships, and applications in sensing, bioimaging, and phototherapy, guiding functional BODIPY‐based ...

Quaternary Pyridinium Salts: A Review

Journal of Oleo Science, 2008
Cationic surfactants are being used in various applications industrially and domestically for a long time. Pyridinium salts come under the category of cationic surfactants. These are unsaturated heterocyclic compounds having different functional groups present either on pyridine ring or at nitrogen atom.

Facile access to pyridinium-based bent aromatic amphiphiles: nonionic surface modification of nanocarbons in water

Beilstein Journal of Organic Chemistry
Efficient water-solubilization of nanocarbons is desirable for both their biological and material applications, but so far has mainly relied on covalent modifications or amphiphiles featuring ionic side-chains. Here, we report a facile 2–4-step synthesis

Pyridinium methylsulfonate: a pseudosymmetric structure

Acta Crystallographica Section E Structure Reports Online, 2001
The title compound, C5H6N+·CH3SO3−, shows pseudosymmetry. More than 80% of the structure is centrosymmetric, whereas the remaining atoms do not fulfil this symmetry, and the structure is actually non-centrosymmetric.

Shedding Light on Synthetic Autocatalysis: From Conventional Closed‐Shell Chemistries to Overlooked Open‐Shell Occurrences

Chemistry – A European Journal, EarlyView.
Why add another catalyst when the product itself holds the power to catalyze its own formation? Autocatalysis in synthetic chemistry enhances reaction efficiency and uncovers novel catalytic behavior across both closed‐shell and open‐shell systems, expanding reactivity and enabling innovative design strategies.

Bioinspired Design and Synthesis of Polyphenolic Star‐Like and Hyperbranched Polyester Models

Chemistry – A European Journal, EarlyView.
Gallotannin‐inspired star‐like and hyperbranched aromatic polyesters were synthesized from D‐glucose and ABn‐type phenolic acid monomers, such as protocatechuic acid. This bioinspired approach afforded polyphenolic polymeric nanoparticles able to encapsulate hydrophobic dyes, opening new perspectives for biobased encapsulation and delivery systems ...
