Synthesis of Dithienylcycloalkene Molecular Switches Enabled by a Bench‐Stable Ti‐Complex
Chemistry – A European Journal, EarlyView.Herein we report a set of cycloalkene‐bridged DTEs with ring sizes ranging from 4‐ to 7‐membered rings. The synthesis of these analogs was performed via a key McMurry coupling step, which was enabled by a practical, bench‐stable Ti(IV)‐complex. Remarkably, it is shown that the strained cyclobutene bridge outperforms other rings, even the most commonly ...

A volumetric three-dimensional digital light photoactivatable dye display
Nature Communications, 2017 Despite living in a three-dimensional world, almost all information in our society is conveyed in a two-dimensional format. Here, the authors provide a technique for the generation of spatially accurate and high-resolution three-dimensional images using ...

Hydantoin-Based Molecular Photoswitches
The Journal of Organic Chemistry, 2015 A new family of molecular photoswitches based on arylidenehydantoins is described together with their synthesis and photochemical and photophysical studies. A series of hydantoin derivatives have been prepared as single isomers using simple and versatile chemistry in good yields.

Fluorescent Diarylethenes With Polar Groups: Synthesis, Spectra, and Optical Microscopy Applications
Chemistry – A European Journal, EarlyView.Blinking green and flashing red: photo‐switchable and photo‐activatable probes emitting green and red light were prepared and applied as bioconjugates in super‐resolution optical microscopy. ABSTRACT The use of photoactivatable fluorescent diarylethenes (fDAEs) in biology‐related light microscopy has been restricted by the lack of probes having freely ...

Visible-range hemi-indigo photoswitch: ON-OFF fluorescent binder for HIV-1 RNA.
Chemical Communications, 2019 A proof-of-principle for the application of hemi-indigo derivatives as RNA binders with photocontrollable fluorescence is presented. The photoswitch binds to the human immunodeficiency virus type 1 (HIV-1) RNA with a significant light-up effect.

Photoswitchable basicity through the use of azoheteroarenes
, 2016 We report an azoheteroarene photoswitchable base, where proton stabilisation in Z isomer is facilitated by neighbouring imidazole rings. A 1.3 unit difference in pKa is observed between the E and Z isomers, which leads to the ability to reversibly ...
