New Approach to Unsymmetric Curcuminoids and Their BF2‐derivatized Fluorophores

ChemistrySelect, Volume 10, Issue 42, November 10, 2025.
The synthesis of asymmetric curcuminoids can be successfully achieved through a ketal intermediate, which is then condensed with one aldehyde, followed by hydrolysis and complexation with BF3·THF. Further condensation with a different aldehyde produces an asymmetric BF2‐curcuminoid derivative.

Recent Developments in Halide Perovskite Nanocrystals for Indirect X‐ray Detection

Advanced Materials Technologies, Volume 9, Issue 20, October 21, 2024.
Perovskite nanocrystals act as scintillators under X‐ray illumination with different conversion yield, stability, or decay times and outperform commercial materials, depending on their composition, host matrix, and luminescence process. Besides the lead halide perovskites, there are lead‐free alternatives providing self‐trapped exciton emission ...
