Extending Certified Spectral Fluorescence Standards for the Calibration and Performance Validation of Fluorescence Instruments to the NIR – Closing the Gap from 750 nm to 940 nm with Two Novel NIR Dyes
Fluorescence methods provide spectral, intensity, polarization, and lifetime information, which contain sample- and instrument-specific contributions. Fluorescence data, comparable across instruments and laboratories, require validated calibration procedures and certified fluorescence standards.
Breakthrough in Stereoselective C(sp³)–H Alkylation: Nickel Catalysis Unlocks Efficient Synthesis of Chiral Heterocycles
The Kong group report a Ni-catalyzed enantioselective C(sp³)–H alkylation of saturated heterocycles using olefins, enabling efficient construction of chiral C(sp³)–C(sp³) bonds. Applications include late-stage drug diversification and concise syntheses of bioactive alkaloids.
