Iminothioindoxyl as a molecular photoswitch with 100 nm band separation in the visible range

Nature Communications, 2019
The design of photoswitches which operate in the visible light regime, show a large separation of absorption bands and are functional in various solvents is challenging.

The role of alkyl substituents in deazaadenine-based diarylethene photoswitches

Beilstein Journal of Organic Chemistry, 2016
Diarylethenes are an important class of reversible photoswitches and often claimed to require two alkyl substituents at the carbon atoms between which the bond is formed or broken in the electrocyclic rearrangement.

Borylated norbornadiene derivatives: Synthesis and application in Pd-catalyzed Suzuki–Miyaura coupling reactions

Beilstein Journal of Organic Chemistry, 2022
The photochromic norbornadiene/quadricyclane system is among the most promising candidates for molecular solar thermal (MOST) energy storage. As in this context there is still the need for new tailor-made derivatives, borylated norbornadienes were ...

Molecular Preorganization Unlocks Reversible Solid‐State Photoconversion in Dianthrylnaphthalene‐Based Molecular Solar Thermal Systems

Angewandte Chemie, EarlyView.
Three dianthrylnaphthalenes were synthesized and investigated for molecular solar thermal (MOST) energy storage. Naphthyl‐based bridging units preorganize the two anthracene moieties face‐to‐face, leading to improved photoisomerization quantum yield (QY) and unlocked bidirectional photoswitching in the solid state compared to previously reported ortho ...

Optical Switches for Lipid Membranes: Computed Molecular Projection Area as a Switch Selection Criterion

Colloids and Interfaces, 2022
Optical switches in lipid membranes are an emerging tool to tune the properties of the bilayer or membrane protein integrated therein. Here, we use simple geometry and physics considerations to deduce structural criteria to design efficient ...
