Cyanine general formula

The compounds obtained in solid state have the general formula [MefSCNf JR., (R-cations of cyanine dyes) and could be embedded into polyvinylchloride matrix. Using the matrix as work element of electrodes shows the anionic function concerning the anionic thiocyanate complexes of Pd, Hg, Zn and the response to sepai ately present thiocyanate and metallic ions is not exhibited. 

In two patents,the preparation of thioether-substituted selena-zoles of the general formula (6) have been described. These are stated to be formed by reaction of halogenoketothioethers with selenoamide components selenoacetamide, selenobenzamide, and A -ethylseleno-urea are given as examples. The resulting selenazoles were not further characterized. They are stated to be starting materials for the preparation of cyanine dyestuffs which are useful photographically.

Cyanines are dyes with a general formula as follows ... 

Related to the cyanine dyes are the merocyanines — a group of compounds which is of equal importance as sensitizers. A general structure is depicted in formula (11) wherein A represents the atoms necessary to complete a heterocyclic nucleus, Y = atoms to complete a carbonyl-containing heterocycle, m = 0 or 1, and n = 0 or a small positive integer.
