Thermal stability improvement of azobenzene for the integration of photochemical and solar thermochemical energy conversion

Case Studies in Thermal Engineering, 2023
Azobenzene is a typical photoisomerization material that is widely used in photochemical energy conversion. However, it's generally operated below 200 °C to avoid thermal decomposition.

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.

Azobenzene-conjugated Propofol-derivatives for Light-control of GABA(A) Receptors in Vision Restoration [PDF]

, 2012
In many cases of retinal degeneration, the deterioration of photoreceptors leaves the downstream inner retinal neurons unstimulated, thus leading to vision loss. Re-initiating visual signaling by means of rendering photosensitivity to these inner retinal

Azobenzene-Avermectin B1a Derivatives for Optical Modulation of Insect Behaviors

, 2021
Naturally occurring avermectins are allosteric modulators of glutamate-gated chloride channels (GluCls) and possess exceptionally potent anthelmintic, acaricidal, and insecticidal activities. Here, we develop photoswitchable azobenzene-avermectin (ABAVM)
