An azobenzene-modified gamma-cyclodextrin stationary phase (Az gamma-CDSP) was prepared and its photo- and temperature-responses for the retention of perylene and pentacene were investigated using a mixture of methanol and water as the mobile phase in micro-HPLC. The retention of perylene slightly increased, whereas that of pentacene significantly decreased by UV light irradiation to Az gamma-C...

The electronic and structural properties of single wall carbon nanotubes (SWCNTs) interacted with 4-amino phenyl-azobenzene were theoretically investigated by using the hybrid DFT (hybrid-density functional theory) calculations. The amount of thermodynamic parameters of this reaction in the gas and aqueous phase suggesting thermodynamic favourability for adsorption of 4-amino phenyl-azobenzene ...

When adorned with n-octyl chains azobenzene is able to disrupt a variety of calcein-loaded phospholipid liposomes. The levels of lysis observed are dependent both on the lipid headgroup and the conformation of the azobenzene compound. In all cases studied, it has been shown that the cis-conformer is more membrane-interactive than the trans-conformer, suggesting that this class of molecule could...

Recent advances in the design of molecular photoswitches have opened up opportunities for storing solar energy strained isomeric structures and releasing heat on demand, culminating thermal (MOST) storage densities over 0.3 MJ kg−1 validating potential achieving battery applications.

We demonstrate reversible photoisomerizaton of azobenzene molecules on a single gold nanoparticle surface with alternating UV and visible irradiation, which is monitored by plasmon resonance Rayleigh scattering spectroscopy and stimulated by the discrete-dipole approximation method.

A three-component supramolecular hybrid system based on host-guest recognition and electrostatic interaction has been developed for a consecutive chiral transfer from an alpha-cyclodextrin to cationic dyes via the bridge of a new azobenzene-grafted Anderson-type polyoxometalate cluster.

This review is devoted to the microscopic mechanism behind photoinduced deformations in side-chain azobenzene polymers. We present the analysis of selected experiments that allows us to propose main criteria for a proper choice of the light induced force. Particularly, we provide convincing evidence that, contrary to a well-spread belief, light induced softening is a very weak accompanying effe...

The reaction of meta- and para-bromomethylene-azobenzenes with 1-methyl-imidazole yields the respective meta-/para-functionalized azobenzenes tagged with an imidazolium group. Similar reactions of ortho- and para-bromo-azobenzene with imidazole and successive quaternation with benzylbromide give the analogues, with an imidazolium group in ortho/para substituted azobenzenes. With the exception o...
