Counterion Exchange Enhances the Brightness and Photostability of a Fluorous Cyanine Dye

Chemistry – A European Journal, Volume 30, Issue 64, November 15, 2024.
While useful tools for studying perfluorocarbons, fluorous soluble fluorophores (fluorofluorophores) are often less bright and prone to rapid photobleaching in the fluorous phase. Here, we utilized a counterion modification on a fluorous pentatmethine dye (FCy5) to promote favorable cyanine character, resulting in a brighter and more photostable ...

Enhanced Organocatalytic Processes through an Engineered Acid‐Base Site Bifunctional Pore in a Zirconium Metal‐Organic Framework

ChemCatChem, Volume 16, Issue 18, September 23, 2024.
The introduction of an acidic and a basic functionality, precisely located, within a metal‐organic framework (MOF) enhances the catalytic activity for Knoevenagel and related condensations. Modified MOF‐808 containing 5‐aminoisophthalic yielded higher rates among all explored materials.

Assessing the estrogenic activity of chemicals present in resin based dental composites and in leachates of commercially available composites using the ER\u3b1-CALUX bioassay

, 2021
: Objective The biocompatibility of resin based dental composites has not yet been fully characterized even though certain monomers used in these composites are synthesized from Bisphenol A (BPA), a well-known estrogenic endocrine disruptor. As a result,

Improvement of the photostabilization of PMMA films in the presence 2N-salicylidene-5-(substituted)-1,3,4-thiadiazole

, 2012
The photostabilization of poly(methy methacrylate) (PMMA) films by 2N-salicylidene-5-(substituted)-1,3,4-thiadiazole compounds was investigated. The PMMA films containing concentration of complexes 0.5% by weight were produced by the casting method from ...
