Abstract

The present invention describes novel dyes, including coumarins, rhodamines, and rhodols that incorporate additional fused aromatic rings. The dyes of the invention absorb at a longer wavelength than structurally similar dyes that do not possess the fused aromatic rings. Many of the dyes of the invention are useful fluorescent dyes. The invention includes chemically reactive dyes, dye-conjugates, and the use of such dyes in staining samples and detecting ligands or other analytes.
