Rosenberg, Martin published the artcileExtended Triangulenium Ions: Syntheses and Characterization of Benzo-Bridged Dioxa- and Diazatriangulenium Dyes, Name: 1,3-Dimethoxybenzene, the main research area is benzo bridged dioxatriangulenium diazatriangulenium dye synthesis fluorescence electrochem property.
The very limited class of fluorophores with long fluorescence lifetime (> 10 ns) and fluorescence beyond 550 nm, has been expanded with two benzo-fused triangulenium derivatives and two cationic [5]-helicene salts. The syntheses of the benzo-bridged dioxa- and diazatriangulenium derivatives (BDOTA+ and BDATA+, resp.) required two different synthetic approaches, which reflect the structural and physiochem. impact on the reactivity of [5]-helicenium precursors. Spectroscopic investigations show that introduction of the benzo-bridge into the triangulenium chromophore significantly red shifts the absorption and emission while maintaining fluorescence lifetimes above 10 ns. The combination of high quantum yield, long fluorescence lifetime, and emission above 600 nm is possible only if the structural aspects of the triangulenium framework are perfectly harmonized to secure a low rate of non-radiative deactivation. The new benzo-bridge may be a general motif to obtain red shifted derivatives of other dye classes.
