Photo-Responsive and Electrically Switchable Mesophases in a Novel Class of Achiral Bent-Core Azo Compounds
نویسندگان
چکیده
The first examples of electrically switchable and photo-responsive mesophases in a novel class of bent-core azo compounds, consisting of only five aromatic rings and no imino functionality (–CHLN–), are reported. The mesophases have been identified as B 1 , B 2 and a new mesophase, B x , on the basis of the results of polarizing optical microscopy, differential scanning calorimetry, X-ray diffraction, and electro-optical response. Preliminary but profound photo-induced effects on the transition temperature from isotropic to the B 2 mesophase of one of the azo compounds are also presented.

Symmetric Bent-core Liquid Crystals of Some Schiff Bases Containing Azo Linkage
The paper presents the synthesis and liquid crystalline properties of some new symmetric bentcore liquid crystals containing a 1,3-dihydroxybenzene central core disubstituted with mesogenic units consisting of three aromatic rings connected through esteric, azomethinic and azo groups. The wings are ended with terminal acyloxy or alkyloxy chains containing 6 to 10 carbon atoms. Compounds were ob...
متن کاملLight-triggered reversible sorption of azo dyes on titanium xerogels with photo-switchable acetylacetonato anchors.
Photo-induced reversible sorption of azo dyes on titania xerogels is observed, which is based on the photo-switchable change of the acetylacetonato anchors in the xerogels. The photoisomerization of azo compounds that regulates many gate-keeper-like host-guest interaction systems is excluded as the determinant.
متن کاملOptical and electrical switching of cholesteric liquid crystals containing azo dye
We propose an optically and electrically switchable cholesteric liquid crystal (ChLC) cell dopedwith a push– pull azo dye. When the proposed ChLC cell is exposed to UV light, it is switched from the focal-conic to isotropic state by a cholesteric-isotropic phase transition through a trans–cis photo-isomerization of push–pull azo dye molecules. With removal of UV light, the ChLC cell will rapidl...
متن کاملVirus-based Photo-Responsive Nanowires Formed By Linking Site-Directed Mutagenesis and Chemical Reaction
Owing to the genetic flexibility and error-free bulk production, bio-nanostructures such as filamentous phage showed great potential in materials synthesis, however, their photo-responsive behaviour is neither explored nor unveiled. Here we show M13 phage genetically engineered with tyrosine residues precisely fused to the major coat protein is converted into a photo-responsive organic nanowire...
