TL;DR: Two xanthene dyes have been synthesized by a convenient and efficient method and exhibited deep-red and near-infrared emissions, high fluorescence quantum yields, and good photostability, rendering them as promising candidates for use in live cell imaging.
Abstract: In this work, two xanthene dyes (H-hNR and TF-hNR) have been synthesized by a convenient and efficient method. These two dyes exhibited deep-red and near-infrared emissions, high fluorescence quantum yields, and good photostability. Their structure–optical properties were investigated by X-ray crystal structure analysis and density functional theory calculations. Live cell imaging data revealed that H-hNR and TF-hNR could rapidly stain both A549 and HeLa cells with low concentrations. The excellent photophysical and imaging properties render them as promising candidates for use in live cell imaging.
