A highly strained non-luminescent dibenzo-acridinium cationic compound is identified that undergoes in acetonitrile light-induced ring closure to create a highly fluorescent, planar, eight-ringed cationic anti-aromatic dye.

In this paper, synthesis and antimicrobial properties of cationic dye were investigated. 4-acetylamino-N-2-aminomethylpyridine-1,8-naphthalimide was reacted with 1-bromobutane as the alkylating agent and a cationic dye was obtained. The final product was purified by column chromatography method. The chemical structure of the novel cationic dye and its intermediates was chracterisized by using F...

The current commercial application of ink-jet reactive inks to cotton fabrics has been through pre-treating with pad liquor prior to printing. In This study made an effort to provide a single phase ink-jet printing process for printing cotton fabric using the novel cationic reactive dye in ink’s formulation. Cotton fabric was printed upon with the novel cationic reactive dye and commercial anio...

Dye pollution represents an important environmental concern, especially from textile industries in the South of Asia. On the other hand, biomass accumulation derived frommussel processing in alimentary industries is also an environmental problem. In this research, these two environmental issues are addressed by proposing the reuse of mussel's protein anchoring threads, the byssus, as disposable...

In this work, organomodified nanoclay has been used as the adsorbent for the removal ofbasic blue 41, cationic dye from an aqueous solution. The performance of the organomodified nanoclay was tested in a batch system under varying pH (2–12), adsorbent dosage (0.1–2 g L-1), initial dye concentration (10–60 mgL-1), and contact time (5- 100 min). The best conditions were achieved at pH of 7,...

pollution of water resources by various pollutants is nowadays a global environmental issue. among the different type of water pollutants, dye represents a major polluting group. in this study, azolla filiculides roots have been used for adsorption of malachite green (mg), a cationic dyed from aqueous solution. in this study, effects of operating parameters such as initial concentration of dye ...

A novel fluorescent system has been assembled by using ATP, surfactant, and a squaraine dye in an aqueous buffer solution. In the system, a cationic surfactant such as cetyl trimethyl ammonium bromide (CTAB) forms a sphere-like micelle, whose positive charge at the surface of the micelle attracts the negatively charged ATP to form a unique organized nanostructure. Such an organized system is sh...

Functionalizations of highly oxidation and hydrolysis stable mono-cationic rhenium bis-arene complexes [Re(η6-C6H6)2]+ are great interest. We directly built up structural features the well-known Hoechst Dye on coordinated arenes as a model for prospective DNA minor groove binding studies. Extensions aromatic unit with functionalized derivatized benzimidazole moieties resulted in deep orange col...

Spectral studies on the interaction of capsular polysaccharide (SPS) isolated from Klebsiella serotype K34, with oppositely charged dyes and surfactants have been reported. The SPS was acidic in nature and induced strong metachromacy (~110 nm blue shift) in the cationic dye pinacyanol chloride (PCYN) which was due to “card-pack stacking” of individual dye monomers on the surface of the polyanio...

Cationic dyes of various natures have been investigated in order to select a dye that is stable under strongly alkaline conditions and applicable for the quantitative extraction-photometric determination higher carboxylic acids. The nature dye, solvent, length hydrocarbon radical acids pH aqueous phase extraction ionic associates with cationic pyronin G were experimentally studied. study substa...
