Photoisomerization in different classes of azobenzene

Chemical Society Reviews, 2012
Azobenzene undergoes trans→cis isomerization when irradiated with light tuned to an appropriate wavelength. The reverse cis→trans isomerization can be driven by light or occurs thermally in the dark. Azobenzene's photochromatic properties make it an ideal component of numerous molecular devices and functional materials.

Azobenzene as a photoswitchable mechanophore

Nature Chemistry, 2023
Azobenzene has been widely explored as a photoresponsive element in materials science. Although some studies have investigated the force-induced isomerization of azobenzene, the effect of force on the rupture of azobenzene has not been explored. Here we show that the light-induced structural change of azobenzene can also alter its rupture forces ...

Mechano-isomerization of azobenzene

Chemical Communications, 2013
We show that ultrasound-induced mechanical force isomerizes an azobenzene centered within a poly(methyl acrylate) polymer from cis to trans configuration without cleaving the azo bond. The isomerization rate was not altered by the polarity of the solvent indicating that the isomerization occurs through a non-polar, inversion transition state.

Enthalpies of formation of cis-azobenzene and trans-azobenzene

The Journal of Chemical Thermodynamics, 1992
The standard (p° = 0.1 MPa) molar enthalpy of formation of crystalline trans-azobenzene was determined from its enthalpy of combustion in oxygen at 298.15 K measured by static-bomb calorimetry. The enthalpy of isomerization: ΔisomH°m(cr, cis → trans)/(kJ · mol−1) = -(49.1 ± 1.0), was measured by reaction-solution calorimetry: the isomerization was ...
