Photostability is one of the key issues in NIR dyes and we have previously reported a photostable CyNA library. Herein we report an ultra-photostable cyanine-based NIR fluorescence library, CyR, utilizing the stability component of CyNA. Efficient solid phase chemistry was also devised to provide a robust synthetic route to the new library. © The Royal Society of Chemistry 2011.
