Fluorescent Hydrogel‐Based Strain Sensor With Machine Learning‐Augmented Performance

Advanced Intelligent Discovery, EarlyView.
Fluorescent hydrogel strain sensor based on carbon quantum dots enabling optical readout of deformation through strain‐dependent emission changes, coupled with Random Forest analysis to capture nonlinear fluorescence‐concentration relationships and identify optimal sensing conditions. Hydrogels are ideal matrices for bio‐integrated wearable sensors due

Covalent Organic Framework Colloids With Core‐Shell Donor/Acceptor Architecture and Ultralong‐Lived Charge‐Separated States

Angewandte Chemie, EarlyView.
Uniform core‐shell colloidal particles of Covalent Organic Frameworks (COFs) are synthesized by a seeded growth of electron‐acceptor COF shells on electron‐donor COF cores. The resulting p‐n heterojunction enables efficient separation of photogenerated charges, which persist for minutes. These core‐shell COFs show efficient CO2 photoreduction to CO and

TADF‐Active Tetrazole Luminophores for Visible‐Light Functionalization of Nanoparticles and Surfaces

Angewandte Chemie, EarlyView.
A series of tetrazoles are reported that undergo 1,3‐dipolar cycloadditions with alkene and alkyne substrates, generating (dihydro)pyrazole products that exhibit thermally activated delayed fluorescence (TADF). The “photo‐click” reactivity of these tetrazoles is leveraged to functionalize nanoparticles and surfaces with TADF‐active chromophores ...

Created Ex Nihilo: A Near‐Infrared Afterglow Luminescent Framework of Imidazole Derivatives for Bioimaging

Angewandte Chemie, EarlyView.
A series of Ir(III) complexes (Ir‐1‐Ir‐4) based on imidazole derivatives provide a new afterglow luminescence mechanism. The work expands the range of afterglow luminescence frameworks to overcome: (i) a lack of new afterglow scaffolds; (ii) the dependence on initial external light activation; and (iii) aggregation‐caused quenching.

Study of Optically Stimulated Luminescence (OSL) of Calcite

O estudo da luminescência opticamente estimulada da calcita é uma área de pesquisa que obtém um foco na resposta luminescente desse mineral quando é estimulado por radiação e, consecutivamente, exposto à luz.

Bistable Switching of π‐Conjugation in a Dithienylethene‐Bridged Luminescent Trityl Diradicaloid

Angewandte Chemie International Edition, EarlyView.
Photoswitches that affect π‐conjugation offer a powerful strategy for external manipulation of luminescent diradicals. Dithienylethene‐linked persistent trityl diradicaloids, DTE‐TTM2 and F6‐DTE‐TTM2, exhibit bistable switching of their optical, electrochemical and magnetic properties.
