A highly fluorescent red-emitting pyrene derivative was synthesized and found to exhibit a large Stokes shift (λem ≈ 610 nm, Δλ ∼ 130 nm, Δν ∼ 4597 cm-1). The probe molecule showed remarkable selectivity to stain the nucleus in both live and fixed cells, with higher sensitivity than commercial dye DRAQ5.
