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
