Modeling Absorption Spectra of Optically Switchable Azobenzenes
Azobenzenes have the unique ability to undergo reversible isomerization between two geometrical isomers (the straight trans form and the bent cis) when exposed to certain wavelengths of light, which provide energy for the change. Thus, when embedded in liquid crystal matrices, azobenzene derivatives can function as optically triggered switches regulating, for example, membrane permeability to g...
متن کاملComputational Modeling of Optically Switchable Azobenzenes
Azobenzenes have a unique ability to undergo reversible isomerization between two geometrical isomer forms (the straight trans and the bent cis) when irradiated with the correct wavelength of UV or visible light. These systems are of interest because of their numerous potential applications as reversible photoswitchable absorbers. The azobenzenes can also be used as terminal groups in nickel di...
متن کاملRobust visible light photoswitching with ortho-thiol substituted azobenzenes.
Introduction of S-ethyl groups in all four ortho positions of azobenzene prevents reduction of the azo group by intracellular glutathione, while enhancing the absorptivity to ~10,000 M(-1) cm(-1) in the blue and green regions of the visible spectrum. cis-to-trans isomerization occurs thermally on the minutes timescale. Further, this substitution pattern permits switching with red light, a color...
متن کاملLight driven reactions of single physisorbed azobenzenes Supplementary information
The configuration of the gas phase molecule is obtained by density functional theory (DFT) geometry optimization using the generalized gradient approximation (GGA) functional as implemented in the Amsterdam Density Functional (ADF) software [1]. Obtained structures are adapted for adsorption on the surface as explained below. For this purpose we use the semi-empirical Parameterized Model number...
متن کاملVisiting the red-light zones with Claudio
Received: 2 August 2005 Revised: 27 September 2005 Accepted: 28 September 2005 Introduction Shortly after Claudio’s permanent appointment at the LSE, he joined me in teaching the advanced MSc option ‘Interpretations of Information’. I had previously co-taught this course with Lucas Introna who had recently moved to Lancaster University. Both Lucas and Claudio shared a love of the work of Martin...
