Abstract
In this paper we describe the synthesis of vinyl-diazine triphenylamines. These compounds exhibit strong green–yellow fluorescence in dichloromethane solution, important emission solvatochromism and acidochromism. Regioselective N-alkylation of these dyes provides cationic compounds that exhibit affinity for double-stranded DNA. Binding to the biopolymer results in a strong bathochromic shift and increase of the emission intensity.
► Vinyl-diazine triphenylamines have been synthesized. ► Strong green–yellow fluorescence in dichloromethane solution is observed. ► Emisision solvatochromism and acidochromism is also observed. ► N-alkylation of these dyes leads to DNA strainers.
