Hydration‐Gated Photoinduced Electron Transfer in BODIPY Dyes

Angewandte Chemie, EarlyView.
Hydration switches photoinduced electron transfer (PET) ON in alkoxy‐coordinated BODIPY dyes via specific hydrogen bonding. This gating yields a fluorescence lifetime span of ∼6 ns, enabling fluorescence lifetime imaging microscopy (FLIM) contrast in live cells and organoids. ABSTRACT Fluorescent probes based on photoinduced electron transfer (PET) are

Advances in Se Wide‐Bandgap Photovoltaics and TexSe1‐x SWIR Photodiodes

Advanced Science, EarlyView.
In this review, fundamental properties and current challenges in Se photovoltaics (PVs) for tandem and indoor PVs and TexSe1‐x alloys for short wave infrared photodiodes are discussed. A case is made for the practicality of elemental chalcogenide optoelectronics, and a pathway toward resolving the key challenges in these respective technologies is ...

Remote Electrostatic Effect between Octahedral Ru/Ir‐Complexes and Aromatic Micelles to Improve Their Photofunctions in Water

Angewandte Chemie, EarlyView.
The aqueous‐state encapsulation of cationic Ru(II)/Ir(III)‐complexes is efficiently demonstrated by anionic aromatic micelles via remote electrostatic interactions. The resulting host–guest composites exhibit enhanced metal‐complex‐based emission (∼3 to 10‐fold) and NIR emission through guest‐to‐guest FRET upon co‐encapsulation.

Additive Manufacturing of High‐Performance Polymers for Extreme Environments

Advanced Science, EarlyView.
Additive manufacturing of high‐performance polymers for extreme environments is critically reviewed through an integrated chemistry‐processing‐structure‐property‐qualification framework. The review compares fused filament fabrication, selective laser sintering, and direct ink writing, linking rheology and thermal history to crystallization, defect ...

Proton‐Induced Perthionitrite‐Mediated Zinc Thiolate Persulfidation

Angewandte Chemie, EarlyView.
A thiolate‐supported zinc thionitrite complex reacts with S8 to insert sulfur at both Zn–S bonds. Although SNO− persulfidation to SSNO− is facile, thiolate persulfidation is less favored in comparison. These thermodynamic differences between S–S‐containing moieties are also observed for free perthiolate and SSNO− anions.

The capacitance and electron transfer of 3D-printed graphene electrodes are dramatically influenced by the type of solvent used for pre-treatment

Electrochemistry Communications, 2019
3D-printing (or additive manufacturing) is presently an emerging technology that promises to reshape traditional manufacturing processes. The electrochemistry field can certainly take advantage of this fabrication tool for sensing and energy-related ...

Solvent effects on photodegradation of CI Reactive Orange 16 by simulated solar light [PDF]

Hemijska Industrija, 2008
Organic solvents may appear in wastewaters and other industrial waste streams containing dyes, therefore, their photodegradation catalyzed by TiO2 should be investigated.

The Reactivity of Benzoates in Mixtures of Water and Aprotic Solvents

Croatica Chemica Acta, 2012
Nucleofugalities of pentafluorobenzoate (PFB), 2,4,6-trifluorobenzoate (TFB), 2-nitrobenzoate, and 3,5-dinitrobenzoate (DNB) leaving groups have been derived from the solvolysis rate constants of the corresponding X,Y-substituted Z-benzhydryl benzoates in 60 % and 80 % aqueous acetonitrile and 60 % aqueous acetone, by applying the LFER equation: log k =
