Abstract:

A series of near-infrared fluorescence probes(6g—6j) with large Stokes shift was synthesized based on carbazole skeleton and characterized by high resolution mass spectrometry(HRMS) and nuclear magnetic resonance spectroscopy(NMRS). The physicochemical and optical properties of the probe show that probe 6j has a wavelength of 668 nm in aqueous solution, a large Stokes shift(146 nm) and a high fluorescence quantum yield(Φ=0.45). The probe 6j was applied to intracellular imaging, and showed an excellent mitochondrial targeting ability(P=0.90). In addition, the probe can fluoresce image in transplanted ovarian cancer tissues of nude mice, providing a new strategy for accurate diagnosis of tumors in clinical practice.
