Synthesis and Evaluation of the Photochemical Properties of Heterocyclic Hemiindigos

This study reports a series of novel heterocyclic hemiindigos (Het-HI) synthesized via the condensation of indoxyl acetate with various heteroaromatic aldehydes. The influence of electronrich and electron-poor heterocycles on the photochemical and…

Divergent Reactivity of E / Z ‐Azobenzene‐Based Phosphine‐Gold Catalysts: Toward an ON‐ON Catalytic Photoswitch Process

This work discloses a strategy for the implementation of ON‐ON organometallic catalytic processes using photoresponsive phosphine ligands. The approach leverages on the regiodivergent reactivity of mono‐ and bimetallic gold complexes that results…

Curcuminoid Derivatives with a Donor‐Acceptor‐Donor Architecture: an Outstanding Platform for Highly‐Efficient Near‐Infrared Electroluminescence and Amplified Spontaneous Emission

Abstract The development of high‐efficiency near‐infrared (NIR) emitters for organic light‐emitting diodes (OLEDs) and organic semiconductor lasers has become an important target in organic photonics. Herein, it is demonstrated that donor‐acceptor…

Quantifying nucleation in flow by video-FLIM

During a precipitation experiment in microfluidics, crystals appear in the flow. Using a molecule that turns fluorescent in the solid phase, these crystals can be counted, measured and their polymorph identified. From this collection of data, the…

Modulation of photoacoustic NIR BODIPY self-assembly in theranostic solid lipid nanoparticles via alpha-group variation: influence on spectral and nanostructural properties

Loading drug nanovectors with a high quantity of near-infrared organic dye considerably increases their absorption cross-section and favors their detection as theranostic agents with photoacoustic imaging. In a previous study, solid lipid…

Structure–Optical Properties Relationships in Cobalt-Based Purple Pigments Used by Robert Delaunay

Following the industrial revolution and the modernization of chemistry, purple became one of the most popular colors in the palettes of late 19th- to 20th-century painters. Among them, Robert Delaunay (1885–1941) was one of the key artists of the…
