In Situ Construction of Imidazopyridinium Fluorescent Labels for Bioconjugation

Angewandte Chemie International Edition, EarlyView.
Chromophore engineering of isoquinoline aldehydes generates TICT‐based fluorogenic dyes for in situ labeling of diverse (bio)molecules with large Stokes shifts compatible with cell imaging. ABSTRACT Simple, efficient transformations of fluorogenic nature that proceed under biocompatible conditions without the formation of byproducts are of high ...
