Smart worm-like micelles responsive to CO₂/N₂ and light dual stimuli [PDF]

, 2017
CO₂/N₂ and light dual stimuli-reponsive worm-like micelles (WLMs) were obtained by addition of a relatively small amount of a switchable surfactant, 4-butyl-4´-(4-N,N-dimethylhexyloxy-amine) azobenzene bicarbonate (AZO-B6-CO₂), sensitive to the same ...

Detailed Photoisomerization Dynamics of a Green Fluorescent Protein Chromophore Based Molecular Switch

International Journal of Photoenergy, 2014
With density-functional-based nonadiabatic molecular dynamics simulations, trans-to-cis and cis-to-trans photoisomerizations of a green fluorescent protein chromophore based molecule 4-benzylidene-2-methyloxazol-5(4H)-one (BMH) induced by the excitation ...

Mechanism and Dynamics of Azobenzene Photoisomerization

Journal of the American Chemical Society, 2003
The excited-state dynamics of trans-azobenzene were investigated by femtosecond time-resolved photoelectron spectroscopy and ab initio molecular dynamics. Two near-degenerate pipi* excited states, S2 and S3,4, were identified in a region hitherto associated with only one excited state.

Unusual Reactivities of ortho-Hydroxy-β-nitrostyrene

Molecules, 2022
Nitrostyrene derivatives are widely used in organic syntheses as a substrate for Michael addition, photoisomerization and cycloaddition. In contrast, ortho-hydroxy derivatives exhibit unusual behaviors in these reactions.

Fluorescent Azobenzene-Containing Compounds: From Structure to Mechanism

Crystals, 2021
The reversible photoisomerization of azobenzenes has been extensively studied to construct systems with optical responsiveness; however, this process limits the luminescence of these compounds.

Azobenzene-Functionalized Ionic Liquids: Light-Responsive Surfactants With Catalytic Potential. [PDF]

ChemistryOpen
Surface‐active imidazolium‐based ionic liquids containing an azobenzene group exhibit different micellization properties upon photoisomerization. Applying a sulfonate tag to the azobenzene moiety profoundly affects the physicochemical behavior of both isomers in water.

Evaluation of the importance of spin-orbit couplings in the nonadiabatic quantum dynamics with quantum fidelity and with its efficient "on-the-fly" ab initio semiclassical approximation [PDF]

, 2012
We propose to measure the importance of spin-orbit couplings (SOCs) in the nonadiabatic molecular quantum dynamics rigorously with quantum fidelity. To make the criterion practical, quantum fidelity is estimated efficiently with the multiple-surface ...
