Cyanine

Among the semi-stable, must be classed cyanine or Leitch's blue, smalt, and Prussian blue. ❋ George Field (N/A)

Unlike the former, cyanine, being composed of two old colours, can lay no claim to originality. ❋ George Field (N/A)

Sulphon cyanine works well with other dye-stuffs, and gives shades which are fast to milling. ❋ Franklin Beech (N/A)

However that may be, in these days both names signify cobalt compounds, coeruleum being a stannate of cobalt, and cyanine a mixture of cobalt and Prussian blue. ❋ George Field (N/A)

Whether these remarks are applicable to cyanine or not is a question for artists to decide: in our opinion, with so many semi-stable original pigments, the introduction of semi-stable compounds is to be deprecated. ❋ George Field (N/A)

Within the last few years, a compound similar to cyanine has appeared, under the name of _Leitch's Blue_. ❋ George Field (N/A)

Hence the peculiar properties of cyanine remain unchanged only so long as the Prussian blue itself, the pigment losing its colour by degrees on exposure to air and light, and gradually assuming the tint of the paler but more permanent cobalt. ❋ George Field (N/A)

Another class of bodies also concerns our subject: the special sensitisers used by the photographer to modify the spectral distribution of sensibility of the haloid salts, _e. g._ eosine, fuchsine, cyanine. ❋ John Joly (1895)

Xanthine, in combination with cyanine, modified by the various juices of plants, communicates in variable proportions orange-yellow, scarlet-red, and red colors to flowers. ❋ George William Septimus Piesse (1851)

For the procuration of this coloring matter the method pursued is exactly as that for the preparation of cyanine. ❋ George William Septimus Piesse (1851)

The agents which generate so easily with cyanine, the rose-red, violet, or green coloration, cannot in any case impart these colors to the yellow substance obtained from flowers. ❋ George William Septimus Piesse (1851)

The precipitate, which possesses a beautiful green color, can be washed with plenty of water, and then decomposed with sulphuretted hydrogen; the coloring matter passes into the watery solution, which is carefully evaporated in a water-bath; the residue is again dissolved in absolute alcohol; and lastly, the alcoholic solution is mixed with ether, which precipitates the cyanine in the form of blue flocks. ❋ George William Septimus Piesse (1851)

Scarlet-red flowers also contain cyanine reddened by an acid, but in such cases this substance is mixed with a yellow coloring matter which we will now describe. ❋ George William Septimus Piesse (1851)

By an attentive comparison of the properties of this coloring matter with those of cyanine, we have found that the rose-red coloring matter is the same as the blue, or at least results from a modification of the same independent principle. ❋ George William Septimus Piesse (1851)

Sodium borohydride is added to commercially available cyanine dyes and the solvent is removed - the one-step process takes less than five minutes. ❋ Unknown (2009)
