Photoinduced Phase Transitions in Rod-shaped Azobenzene with Different Alkyl Chain Length

Photoinduced phase transitions in liquid crystalline systems

In recent years, a field of research that is growing steadily is the photoinduced phenomenon in which the incident light itself brings about molecular ordering/ disordering of the liquid crystalline system. This particular aspect of photonics, in which light can be controlled by light as a stimulus, is being proposed as the future technology for high-speed information processing and photochromi...

Alkylcyanoacrylate drug carriers: I. Physicochemical characterization of nanoparticles with different alkyl chain length

Alkylcyanoacrylate particles were physico-chemically characterized in terms of size, surface charge, zeta potential, interaction with charged serum components and surface hydrophobicity as relevant parameters influencing the in vitro interaction with cells in culture and the in vivo organ distribution and fate after intravenous administration. Methyl-, ethyl-, isobutyland isohexylcyanoacrylate ...

Photoinduced Deformations in Azobenzene Polymer Films

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...

Effect of heat and film thickness on a photoinduced phase transition in azobenzene liquid crystalline polyesters

Photoinduced isothermal phase transitions of liquid-crystalline macrocyclic azobenzenes.

Liquid-crystalline macrocyclic compounds, tethered by two or three azobenzenes bearing alkoxy side chains, exhibit isothermal phase transitions from liquid-crystal to isotropic as well as from crystal to isotropic phases upon light irradiation due to the drastic conformational change of their macrocyclic backbone.
