Threading a Linear Molecule Through a Macrocycle Thanks to Boron: Optical Properties of the Threaded Species and Synthesis of a Rotaxane

Angewandte Chemie, Volume 136, Issue 12, March 18, 2024.
Boron‐containing species were threaded through macrocycles bearing a 2,2’‐biphenol unit. The new threaded species exhibited interesting fluorescence features with quantum yields up to 91 % and an enhanced photostability. Their properties were rationalized with quantum chemistry to unravel the vibronic contributions.

Amplified Heavy-Atom Free Phosphorescence from meta-Dimethoxy Difluoroboron β‑Diketonate Charge-Transfer Materials

, 2019
Difluoroboron β-diketonate materials are used for biomedical oxygen-sensing applications. These fluorophores show both fluorescence (F) and phosphorescence (P) when the dye is embedded in a polymer matrix.

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.

Effects of α‑Substitution on Mechanochromic Luminescence and Aggregation-Induced Emission of Difluoroboron β‑Diketonate Dyes

, 2016
Though the effects of arene substituents on difluoroboron β-diketonate (BF2bdk) mechanochromic luminescence (ML) are known, substitution at the α carbon of the dioxaborine ring has yet to be carefully investigated.
