π‐Extended COUPY Fluorophores for Targeted Near‐Infrared Fluorescence and Lifetime Imaging in Live Cells

open access: yesAngewandte Chemie, EarlyView.
π‐Extended COUPY dyes, obtained by vinylogation of coumarin‐based COUPY scaffolds, shift absorption, and emission deep into the NIR region while preserving compactness and synthetic accessibility. These bright, photostable dyes enable live‐cell imaging, FLIM, and site‐specific peptide conjugation, offering a modular platform for targeted bioimaging and
