Synthesis and Spectroscopic Properties of Diarylethene‐Subporphyrinoid Hybrids [PDF]

open access: yesChemPhysChem
AbstractTwo novel diarylethene‐fused subporphyrinoids were prepared and characterized. A mono diarylethene derivative was obtained via a statistical condensation reaction with 2 eq. of 1,2‐dicyanobenzene and 1 eq. of thiophene‐disubstituted butenedinitrile. The symmetric triply diarylethene‐fused subporphyrazine was synthesized via a cyclotrimerization

Light-Driven Out-of-Equilibrium Helicity Control in a Diarylethene-Helicene Photosystem. [PDF]

open access: yesAngew Chem Int Ed Engl
Distinct energy landscapes of different helicities in the open and closed states of a diarylethene–helicene photoswitch enable a light‐driven energy ratchet. Helix inversion occurs selectively in the closed form, and the resulting helicity is transferred and kinetically trapped upon ring opening, generating a persistent out‐of‐equilibrium chiral state ...

Holography with Photochromic Diarylethenes [PDF]

open access: yesMaterials, 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]

open access: yesACS 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 ...

Gated Photochromism of 1,2-Diarylethenes [PDF]

open access: yesOrganic 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 observed.

A Suzuki Approach to Quinone-Based Diarylethene Photochromes

open access: yes, 2020
Diarylethene photochromes show promise for use in advanced organic electronic and photonic materials with burgeoning considerations for biological applications; however, these compounds typically require UV light for photoswitching in at least one ...

DYOTROPIC REARRANGEMENT OF DIARYLETHENES

open access: yesModern Technologies and Scientific and Technological Progress, 2021
The analysis of the reaction of dyotropic rearrangement of diarylethenes, which limits the fatigue resistant of this class of photochromic compounds, has been carried out.

Visualization and Comprehension of Electronic and Topographic Contrasts on Cooperatively Switched Diarylethene-Bridged Ditopic Ligand

open access: yesNanomaterials, 2022
Diarylethene is a prototypical molecular switch that can be reversibly photoisomerized between its open and closed forms. Ligands bpy-DAE-bpy, consisting of a phenyl-diarylethene-phenyl (DAE) central core and bipyridine (bpy) terminal substituents, are ...
