Abstract

Tetramethylene-2,2'-bis(1,3,3-trimethyl-(3H)-indolium),  -3-ethylbenzothiazolium, -1-methyl- quinolinium, and -1-methyl- and -1-butylbenz[c,d]indolium salts were synthesized  starting  from them trimethinecyanines containing an ethylene bridging group in the α,α'-positions of the chromophore have been prepared. These compounds are  converted to their analogs containing a vinylene  group  by  the action of benzoquinones. In the case of thiacarbocyanines the effect of the indicated bridging groups on the conformation and protonation route of the carbocyanines has been studied. The chromaticity of the dyes has been investigated.
