Abstract

The syntheses and biological applications of two novel fluorescent 9-phenylethynylpyronin analogues containing either carbon or silicon at the position 10 are reported. Both fluorescent probes exhibited a relatively strong fluorescence in methanol and phosphate buffer saline in the near-infrared region (705–738 nm) upon irradiation of either of their absorption maxima in the blue and red regions. The compounds showed high selectivity ...
