Simon, P. published the artcileNew NIR dyes for ammonia sensing, Computed Properties of 606-55-3, the publication is Sensors and Actuators, B: Chemical (2003), 90(1-3), 9-14, database is CAplus.

Three series of new cyanine dyes were synthesized and the visible-NIR spectra of the dyes were measured and interpreted by semi-empirical methods of quantum chem. As a basic building block for the synthesis, 4-(dimethylaminomethylene)-5-oxo-2-furfurylidenedimethyliminium perchlorate (I) was used. The dyes were prepared by condensing I with appropriate salts. The tests for sensitivity to ammonia showed that mono-substituted dyes III are reversibly sensitive to ammonia in ethanol solutions The dyes exhibit a peak at 620-680 nm arising from the interaction with ammonia and, hence, these dyes are promising as chem. transducers for distributed fiber-optic ammonia sensors.

Koenigstein, Christian published the artcileOrigin of the high-energy emission of 1,1′-diethyl-2,2′-cyanine dye, Recommanded Product: 1-Ethyl-2-methylquinolin-1-ium iodide, the publication is Journal of Photochemistry and Photobiology, A: Chemistry (1994), 84(3), 245-8, database is CAplus.

In addition to the yellow emission ascribed to the J aggregates of 1,1′-diethyl-2,2′-cyanine, this compound also exhibits a high-energy emission around 400 nm in dilute aqueous solutions (c<10^-3 mol l^-1). It was found using time-resolved emission measurements that protonation of 1,1′-diethyl-2,2′-cyanine is responsible for this emission. At pH<4, the excited state protolytic reaction competes with ground state protonation. Both pathways give the same excited species, luminescing at 400 nm. The non-protonated form shows only weak fluorescence. The excited state lifetime of the protonated form is 4.5 ns.

Ichijo, Keisuke published the artcileCrystal Structures and Optical Properties of Cyanine Dyes Depending on Various Counter Anions, Product Details of C12H14IN, the publication is ACS Omega (2021), 6(42), 28421-28431, database is CAplus and MEDLINE.

In this study, cyanine cations with various counter anions were prepared as examples of ionic materials constructed using charged π-conjugated systems. A series of ion pairs was obtained by anion exchange reactions using iodide salts of carbocyanine dyes. The optical properties were measured by UV/vis absorption and fluorescence spectroscopy; measurements performed in CHCl₃ (less-polar solvent) were altered by the influence of the counter anions. The packing structures of nine crystals were determined by single-crystal X-ray anal. Moreover, the locations of the anions relative to the cations were stabilized by hydrogen bonding and categorized into two types. In addition, delocalization of the neg. charge of the anions on cyanine cations was explained by d. functional theory calculations Furthermore, it was concluded that the stack formation of cyanine cations depends on the size and structure of the anions.

Bajorek, Agnieszka published the artcileNovel, N-ethyl-2-styrylquinolinum iodides as fluorophores for monitoring of polymerization process, Part I, Synthetic Route of 606-55-3, the publication is Dyes and Pigments (2009), 82(3), 372-378, database is CAplus.

A series of p-substituted 2-styrylquinolinium iodides were prepared by the condensation of N-ethyl-2-methylquinolinium salts with p-substituted benzaldehydes. The spectroscopic properties of the styryl quinolinium dyes are characterized in organic solvents of varying polarities. The electronic absorption and fluorescence emission spectra of the dyes demonstrate their high sensitivity to the nature of substituents introduced into the aromatic ring. The dyes were investigated as fluorescent probes for monitoring the progress of the photochem. initiated free-radical polymerization of a mixture of 2-ethyl-2-(hydroxymethyl)-1,3-propanediol triacrylate and 1-methyl-2-pyrrolidinone. During the course of the polymerization an increase in the fluorescence intensity of the dyes by at least one order of magnitude was recorded; a feature which renders the dyes as good fluorescent probes for such polymerization reactions. The term “probe sensitivity” has been defined and appears in the range from 0.08 to 11 for the styryl dyes.
