Abstract

The reaction of selenoflavone with methylmagnesium iodide and with methyl o-nitrobenzenesulfonate was used to synthesize 4-methyl- and 4-methoxyselenoflavylium salts, from which a number of polymethine dyes of symmetrical structure were obtained. The selenoflavylocyanines have a considerably deeper color than other polymethine dyes with the same chromophore length.
