Illuminating Lead Coordination in Perovskite Precursors via Fluorescence Spectroscopy
Fluorescence spectroscopy captures the subtle yet critical changes in multi‐scale lead coordination environments in perovskite precursor. By systematically probing halide‐based [PbX6]⁴⁻ octahedra under varied solvents and cations, this work reveals “fingerprints” charting the evolution from low‐dimensional clusters to 3D frameworks.

Oxidative Rearrangements of the Alkaloid Intermediate Geissoschizine
19E‐geissoschizine is a key precursor in the biosynthesis of monoterpene indole alkaloids such as strychnine, ibogaine, and vinblastine. Using enzymatic assays and gene silencing, three CYPs were identified from C. roseus that oxidize this compound to four alkaloid scaffolds: strychnos, sarpagan, akuammiline, and mavacurane. Mutational analysis reveals

In a proof‐of‐concept study, it was for the first time shown that planar chiral trans‐cycloalk‐2‐enones, such as 2, can be formed enantioselectively from their cis‐isomers by triplet energy transfer from a chiral catalyst. Computational studies performed with cyclohept‐2‐enone and enone 1 provided invaluable insights into the mode of action of the ...

Azobenzene‐Oxindole Photochromic Dyads
A novel photochromic azobenzene‐oxindole dyad is reported. The combination of the two switches promotes drastic molecular geometry changes and allows for precise NMR quantification. This enables the study of the photokinetic behavior under different irradiation conditions and the discovery of a unique photokinetic relationship between the two ...
