A general highly efficient synthesis of biocompatible rhodamine dyes and probes for live-cell multicolor nanoscopy
Abstract
Rhodamines are privileged fluorescent dyes for labelling intracellular structures in living cells. Here, the authors present a facile protecting-group-free synthesis permitting generation of a wide range of symmetrical and unsymmetrical 4-carboxyrhodamines covering the whole visible spectrum.
