Synthesis of a set of new, azide bearing, biorthogonally applicable fluorogenic dyes with
large Stokes shifts is presented herein. To assess the fluorogenic performance of these new
dyes we have labeled a genetically modulated, cyclooctyne-bearing protein in lysate
medium. Studies showed that the labels produce specific signal with minimal background
fluorescence. We also provide theoretical insights into the design of such fluorogenic labels.
