Azobenzene photoswitches in bulk materials

Physical Review E, 2008
A nonadiabatic two-scale quantum-classical dynamics method is developed to allow for dynamical simulation of photoinduced processes and reactions in chemically complex condensed-matter systems such as photosensitive liquid crystals. A first application to photoswitching of azobenzene in the bulk reveals not only valuable insights into the excited-state

Rotational Barriers in Azobenzene and Azonaphthalene

The Journal of Physical Chemistry A, 2010
Theoretical predictions of rotational barriers for pi-conjugated substituents of aromatic rings sometimes significantly overestimate the corresponding experimental values. In this work, the rotational barriers in benzaldehyde, azobenzene, and azonaphthalene are studied by DFT calculations employing a variety of exchange-correlation functionals and ...

Direct ortho-mercuration reactions of azobenzene and ortho-substituted azobenzenes

Journal of Organometallic Chemistry, 1976
Abstract The mercuration of azobenzene occurred exclusively in the ortho -position to yield 2-chloromercuriazobenzene and a mixture which on iodination gave 2,2'and 2,6-diiodoazobenzene. Ten other ortho -substituted azobenzenes were mercurated and mercuration was found to occur predominately in an ortho -position.

Photoresponsive Dendritic Azobenzene Peptides

ChemBioChem, 2001
Two dendritic peptides containing a branched lysine core and up to eight azobenzene moieties in the periphery were synthesized on solid support employing the omega-amino acid 4-(aminomethyl)phenylazobenzoic acid. With an additional peptidic tail consisting of an oligolysine portion, water solubility was achieved for the dendrimers, which allowed for ...

Synthesis and isomerization of azobenzene dendrimers

Photochemical & Photobiological Sciences, 2003
3,3',5,5'-Tetramethoxyazobenzene and related meta-substituted azobenzene dendrimers show the first evidence of the dendritic effect on trans-to-cis photoisomerization; the thermodynamic parameters for cis-to-trans isomerization have been determined.

Laterally Mounted Azobenzenes on Platforms

The Journal of Organic Chemistry, 2015
Triazatriangulenium ions have previously been used as platforms to prepare self-assembled monolayers of functional molecules such as azobenzenes with vertical orientation and that are free-standing on gold surfaces. We have now prepared azobenzenes that are spanned between two posts which are attached on two platforms.
