Azobenzene is a well‐known derivative of stimulus‐responsive molecular switches and has
shown superior performance as a functional material in biomedical applications. The results …

Ultrafast photochemical reactions in liquids occur on similar or shorter time scales compared
to the equilibration of the optically populated excited state. This equilibration involves the …

Azobenzene undergoes trans→ cisisomerization when irradiated with light tuned to an
appropriate wavelength. The reverse cis→ transisomerization can be driven by light or …

Photochromism is defined as a reversible transformation in a chemical species between two
forms, and in these reversible processes, at least one pathway is induced by …

Femtosecond transient absorption measurements of the photoisomerization of azobenzene
excited at 435 nm in the long-wavelength formation with a dominating 170 fs and a weak 2 …

Most symmetric quadrupolar molecules designed for two-photon absorption behave as
dipolar molecules in the S1 electronic excited state. This is usually explained by a breakup …

The electronic relaxation and isomerization mechanism of trans-azobenzene after the S2
(ππ*)← S0 photoexcitation were investigated in solution by steady-state and femtosecond …

▪ Abstract Time-resolved infrared (IR) and Raman spectroscopy elucidates molecular
structure evolution during ultrafast chemical reactions. Following vibrational marker modes …

We have simulated the photoisomerization dynamics of azobenzene, taking into account
internal conversion and geometrical relaxation processes, by means of a semiclassical …

Controlling the activity of proteins with azobenzene photoswitches is a potent tool for
manipulating their biological function. With the help of light, it is possible to change binding …
