Photoisomerization and Optoelectronic Properties of Organoboron Compounds [PDF]
, 2020 This thesis focuses on the investigation of the photo-induced isomerization of organoboron compounds, as well as their optoelectronic properties. Despite extensive explorations in the relationship between molecular structure and their photoreactivity ...

Synthesis of N-acetyl diazocine derivatives via cross-coupling reaction
Beilstein Journal of Organic ChemistryDiazocines are photoswitches derived from azobenzenes by bridging the two phenyl rings in ortho position with a CH2CH2 group forming an eight membered (diazocine) ring.

Crossing the Threshold: Using Photostationary States to Control Supramolecular Polymerisation
Angewandte Chemie International Edition, EarlyView.Intermediate photostationary states regulate the concentration of a polymerisation‐active monomer. Once the nucleation threshold is crossed, small wavelength‐dependent changes in isomer composition are amplified into a non‐linear supramolecular assembly response.

Catalysis by a Metastable Photoswitchable Cage
Angewandte Chemie International Edition, EarlyView.A self‐assembled heteroleptic cage is formed by isomerizing a photoswitchable ligand to its metastable Z‐isomeric form (Z‐1) using green light and combining with a non‐switchable ligand (2) and palladium(II) ions. The metastable [Pd2(Z‐1)2(2)2]4+ cage is an out‐of‐equilibrium self‐assembled catalyst, and can be reversibly assembled and disassembled ...

Photo‐Switchable FRET‐Enabled Flexible Luminescent Films for Multilevel Optical Security
Carbon Energy, EarlyView.A light‐gated FRET composite integrates a Tb‐Phen donor and a spiropyran acceptor in a polyurethane matrix. Under 365 nm light, spiropyran is transformed into merocyanine, creating spectral overlap with Tb3+ emission and activating energy transfer. Visible light reverses the switch, restoring green emission and enabling reversible multilevel optical ...
