Angew Chem Int Ed Engl. 2019 Jul 1;58(27):8974-8976. doi: 10.1002/anie.201902956. Epub 2019 May 24.

Abstract

Polymethine bridges in cyanine dyes may be constrained by setting them into edge-fused ring systems, or extended by conjugation with carefully chosen heterocycles. Recent studies have shown that modifications like these can give significantly brighter dyes with red-shifted absorbance and emission maxima.

Keywords: cyanine; dyes; fluorescence; heptamethine.
