A Large Stokes’ Shift Styryl Pyridinium Derivative with a Stable Green-emission for Mitochondria Imaging in Live Cells
Abstract
Green-emitting styryl pyridinium probe (EPN) was developed for live-cell imaging applications. EPN exhibited a large Stokes shift (Δλ ≈150 nm) due to efficient ICT across π-acceptor system. Probe exhibited exceptional biocompatibility and excellent specificity to cellular mitochondria. EPN exhibited a great photostability to continuous irradiation and exhibited a stable emission in cells up 5 hours post-staining,
