Multi-signal-based self-calibrating biosensors have become a research focus due to their superior accuracy and sensitivity in recent years. Herein, the potential-resolved differential ECL immunoassay based on dual co-reactants regulation was developed. Meso-tetra(4-carboxyphenyl)porphyrin (TCPP) functionalized zirconium dioxide (ZrO) composites (TCPP-ZrO) was first synthesized using TCPP as the luminophore and ZrO as the enhancer and stabilizer.

A novel regioselective manganese(III)-mediated radical cascade cyclization of N-propargyl enamides with various H-phosphine oxides, H-phosphinates and H-phosphonates was developed. Mechanistic studies show that the reaction is mainly composed of the selective addition of phosphonyl radical to C≡C bond and the intramolecular 6--trig cyclization of vinyl radical. Utilizing this protocol, we successfully synthesized a diverse range of 3-phosphorylpyridines in high efficiency with good functional group compatibility and simple operation.

As the third largest class of dyes in the world, triphenylmethane dyes are widely applied in colorimetric sensing. However, triphenylmethane dyes are commonly nonfluorescent, which limits their sensing applications. It is worthwhile to study the fluorescence off/on control of triphenylmethane dyes and promote the applications of triphenylmethane dyes in sensing technology.

The relative reactivity and cis/trans selectivity of the intramolecular [3+2] cycloaddition (IM32CA) reactions of nitrile oxide (NO), azide (AZ), nitrile sulfide (NS) and nitrile ylide (NY), leading to functionalized heterocycles are studied within the Molecular Electron Density Theory. The kinetically controlled IM32CA reactions are predicted to be cis stereospecific, while the reaction feasibility follows the order NY > NS > NO > AZ with the respective activation Gibbs free energies of 13.7, 17.
