TL;DR: Novel rhodamine dyes excitable with 630 nm laser light and emitting at around 660 nm have been developed and Syntheses of lipophilic and hydrophilic derivatives starting from the same chromophore-containing scaffold are described.

TL;DR: Four novel red fluororescent dyes are reported on, including the first phosphorylated dye, created by combining a rigidized rhodamine backbone with various polar groups, which exhibit large fluorescence quantum yields and improved NHS ester stability.

TL;DR: This work presents a general strategy to covalently link a synthetic organic fluorophore simultaneously to a photostabilizer and biomolecular target via unnatural amino acids, and is convinced that the presented scaffolding strategy and the improved characteristics of the conjugates in applications will trigger the broader use of intramolecularPhotostabilization and help to emerge this approach as a new gold standard.

TL;DR: In this article, a general synthetic route to carbopyronines with functional groups variable in the final steps of the synthesis or in the resulting fluorescent dye is presented, and a multistep synthesis of the dye starting from a simple precursor and utilizing a single temporary protective group is described.

TL;DR: In this article, hydrogenated rhodamines, carbopyronines, carbo-, silico-, and germanorhodamines with absorption maxima in the range of 530-640 µm were used for specific labeling of living cells.
