Photoinduced Mechanical Cloaking of Diarylethene‐Crosslinked Microgels
Advanced Materials, 2023 AbstractThe serial connection of multiple stimuli‐responses in polymer architectures enables the logically conjunctive gating of functional material processes on demand. Here, a photoswitchable diarylethene (DAE) acts as a crosslinker in poly(N‐vinylcaprolactam) microgels and allows the light‐induced shift of the volume phase‐transition temperature ...

Diarylethene‐Based Photoswitchable Inhibitors of Serine Proteases [PDF]
Angewandte Chemie International Edition, 2021 AbstractA bicyclic peptide scaffold was chemically adapted to generate diarylethene‐based photoswitchable inhibitors of serine protease Bos taurus trypsin 1 (T1). Starting from a prototype molecule—sunflower trypsin inhibitor‐1 (SFTI‐1)—we obtained light‐controllable inhibitors of T1 with Ki in the low nanomolar range, whose activity could be modulated

Gated photochromism of 1,2-diarylethenes [PDF]
Organic Letters, 2007 A dithienylethene derivative containing a cyclobutene-1,2-dione skeleton does not exhibit photochromic properties. However, when both ketone functions are protected with cyclic acetal groups, photochromic behavior is ...

Combined Photopolymerization and Localized Photochromism by Aza-Diarylethene and Hemiindigo Synergy. [PDF]
Adv MaterMolecular photoswitches produce light‐controlled changes at the nanometer scale and can therefore be used to alter the states and behavior of materials in a truly bottom‐up fashion. Here an escalating photonic complexity of material property control with

Holography with Photochromic Diarylethenes [PDF]
Materials, 2019 Photochromic materials are attractive for the development of holograms for different reasons: they show a modulation of the complex refractive index, meaning they are suitable for both amplitude and phase holograms; they are self-developing materials, which do not require any chemical process after the light exposure to obtain the final hologram; the ...

Electrochemical and Photochemical Cyclization and Cycloreversion of Diarylethenes and Diarylethene-Capped Sexithiophene Wires [PDF]
ACS Nano, 2011 A combined theoretical and experimental study was performed on diarylethenes and diarylethene-capped sexithiophenes aiming at an improved understanding of the electrochemical and photochemical ring-opening and ring-closing mechanisms. Theoretical calculations, based on DFT and TDDFT, suggested that the spatial distribution and the occupancy of the ...
