Microwave assisted and in-situ generated palladium nanoparticles catalysed desulfitative synthesis of cross-biphenyls from arylsulfonyl chlorides and phenylboronic acids

Results in Chemistry, 2021
A microwave assisted reaction protocol for Suzuki–Miyaura cross-coupling has been developed. Substituted arylboronic acids and arylsulfonyl chlorides coupled under microwave irradiation (MWI) to produce cross-biphenyls in high yields under aerobic ...

Investigation of Halogen Substitution Effects in π‐Conjugated Organic Ligands of Chiral Hybrid Perovskites on Their Chiroptical Activity

Advanced Functional Materials, EarlyView.
The role of novel thiophene‐based ligands with halogen substitutions in enhancing the chiroptical and optoelectronic properties of 2D chiral HOIPs has been investigated. By tailoring ligand design, enhanced CD and CPL properties are achieved, with improved CPL discrimination in photodetectors.

Molecular Design of Highly Efficient Heavy‐Atom‐Free Near‐Infrared Cyanine Photosensitizers for Fluorescence Image‐Guided Photodynamic Therapy of Solid Tumors

Advanced Healthcare Materials, EarlyView.
Highly efficient heavy‐atom‐free NIR photosensitizers based on a heptamethine cyanine platform were developed for image‐guided photodynamic therapy. Both in vitro and in vivo results revealed that the R820‐3 photosensitizer with a highly twisted molecular structure exhibited potential for NIR fluorescence image‐guided photodynamic cancer therapy ...

Developmental exposure to non-dioxin-like polychlorinated biphenyls promotes sensory deficits and disrupts dopaminergic and GABAergic signaling in zebrafish

Communications Biology, 2021
Nadja Brun et al. characterize the impact of early exposure to polychlorinated biphenyls on neural development and behavior in zebrafish. Their results demonstrate that developmental exposure to these chemicals promotes sensory deficits and disrupts ...

Counterintuitive Fluorescence Blue Shift in Symmetry Breaking Dicationic Bis(indolium) with Two‐Photon Absorption Properties for NIR Living Cell Imaging

Advanced Materials, EarlyView.
Highly water‐soluble dicationic bis(indolium) dyes have been prepared, showing excellent two‐photon absorption and light emission. Their fluorescence behavior discloses an unusual increasing blue shift with increasing solvent polarity, which, in parallel, is beneficial for enhanced detection in biological media.
