Given that proteins with minor variations in amino acid sequences cause distinct functional outcomes, identifying and quantifying similar proteins is crucial, but remains a long-standing challenge. Herein, we present a two-dimensional orthogonal fluorescence and chemiluminescence design strategy for the probe DCM-SA, which is sequentially activated by albumin-mediated hydrolysis, exhibiting light-up fluorescence and photo-induced cycloaddition generating chemiluminescence, enabling orthogonal signal amplification for discrimination of subtle differences between similar proteins. By orthogonalizing these dual-mode signals, a two-dimensional work curve of fluorescence and chemiluminescence is established to distinguish and quantify similar proteins HSA and BSA.

Vicinal bis(tetraarylphosphonium) salts have scarcely been reported in the literature. In this study, we demonstrate that visible-light-induced difunctionalization of -trifluoromethylsulfonylated diaryliodonium salts conveniently furnishes bis(phosphonium) salts without additional catalysts or photoinitiators. The methodology establishes a practical platform for the preparation of bis(phosphonium) salts using readily available tertiary phosphines.

The Heck reaction is one of the most well-known C-C (carbon-carbon) coupling reactions and was identified with the Nobel Prize in Chemistry in 2010. These reactions have been broadly utilized to prepare a different spectrum of heterocycles with applications in agrochemical and pharmaceutical industries. These reactions are commonly catalyzed by palladium due to its tolerance and expansive variousness of functional groups, which bears a remarkable power in creating C-C bonds.

Nanoconfinement at the interface of heterogeneous Fenton-like catalysts offers promising avenues for advancing oxidation processes in water purification. Herein, we introduce a template-free strategy for synthesizing nanoconfined catalysts from municipal sludge (S-NCCs), specifically engineered to optimize reactive oxygen species (ROS) generation and utilization for rapid pollutant degradation. Using selective hydrofluoric acid corrosion, we create an architecture that confines atomically dispersed Fe centers within a micro-mesoporous carbon matrix in situ.
