Synthesis of azo dye derived from mango seed kernel and an investigation of its use on polyamide fiberOrganol brown dye was synthesized by coupling of active ingredient from mango seed kernel with diazonium salt. The resultant dye was characterized by UV, IR and Mass spectroscopy. The dyeing ...
Synthesis of Azo Dye Containing Polymers and Application for Optical Data Storagetrans-cis isomerizationdisperse red 1optical data storagePoly(malonic ester) with two symmetrical azobenzene groups (PDR1) was synthesized, and azo dye-doped polymer (ADP) thin films were prepared using PDR1 and matrix...
Substituents on the benzene, usually at the para position, affect the resulting colour of the molecule due to their contributions to the HOMO/LUMO orbital energies. Take a look at theazo-dyespage to view a selection of dyes and their HOMO/LUMO orbital representations. ...
Zeolites are used in water purification; removal of hazardous metal ions; removal of organic pollutants from wastewater; removal of ammonia, nitrogen, and phosphates from wastewater; applications in gas treatment; adsorption of volatile organic compounds (VOC); CO2adsorption; adsorption of other gases;...
Introduction of the F-atom into the aromatic moiety of azo-dye compounds leads to a variation of the charge distribution and consequently to different molecular stackings. Accordingly, the mesogenic behaviors in the solid state are different....
The voltage holding ratio value of a photoaligned LC cell was found to be even higher than for a rubbed PI layer, which enables the applications of azo dyes as aligning layers in active matrix liquid crystal displays. The thermal stability of the photoaligned azo dye layers is sufficiently ...
The synthesis of transparent hybrid organic-inorganic coatings obtained from condensation between alkoxysilane containing grafted dyes (azo dyes or phthalocyanines) and metal alkoxides precursors has been performed. The Red 17 azo dye, known for its high second order polarisability, was bonded to the ...
The UV-visible spectral data have also been discussed in terms of structural property relationship. All the disperse azo dyes were applied on polyester textile fibers. The percentage dye bath exhaustion and fixation on the polyester fibers have been found to be very good. Moderate to very good ...
