The first observation of azo-hydrazone and cis-trans tautomerisms for disperse yellow dyes and their nickel(ii) and copper(ii) complexes.
Summary of "The first observation of azo-hydrazone and cis-trans tautomerisms for disperse yellow dyes and their nickel(ii) and copper(ii) complexes."
Azo-hydrazone and cis-trans tautomerisms have been firstly observed between two disperse yellow dyes (cis/trans-HL(1) and cis-HL(2)) and three neutral dye-metal complexes (one mononuclear Ni(II) complex 3 and two Cu(II) coordination polymers 4 and 5 formulated as [Ni(trans-L(1))(2)(CH(3)OH)(2)].2H(2)O, [Cu(cis-L(1))(2)](n) and [Cu(L(3))(H(2)O)](n)).

Medical and Biotech [MESH] Definitions
P-aminoazobenzene
Used in the form of its salts as a dye and as an intermediate in manufacture of Acid Yellow, diazo dyes, and indulines.
Observation
The act of regarding attentively and studying facts and occurrences, gathering data through analyzing, measuring, and drawing conclusions, with the purpose of applying the observed information to theoretical assumptions. Observation as a scientific method in the acquisition of knowledge began in classical antiquity; in modern science and medicine its greatest application is facilitated by modern technology. Observation is one of the components of the research process.
Hair Dyes
Dyes used as cosmetics to change hair color either permanently or temporarily.
Lissamine Green Dyes
Green dyes containing ammonium and aryl sulfonate moieties that facilitate the visualization of tissues, if given intravenously. They have mostly been used in the study of kidney physiology.
Yellow Fever Vaccine
Vaccine used to prevent YELLOW FEVER. It consists of a live attenuated 17D strain of the YELLOW FEVER VIRUS.
