    • 2O (Φ = 0.90) for compound 6; ICG in DMSO (Φ = 0.013) for compound 7. Quantum yields were calculated according to: Demas, J. N.; Crosby, G. A. Phys. Chem. 1971, 75, 991. Absorption spectra were recorded with a PerkinElmer UV-vis-NIR spectrophotometer, fluorescence spectra were obtained with a PerkinElmer LS55 spectrofluorometer.

    • For fluorescence microscopy, stock solution of the compound 6 was prepared in ethanol and then diluted to the final concentration with PBS buffer in order that ethanol content in then labeling solution was <1% (v/v). CHO cells stably transfected with the intronless human genomic clone G-21
    • 2+. Cells were incubated with 2 μM of compound 6 for 5 min at 4 °C in order to inhibit endocytosis. To competitively wash off the compound 6, PBS containing 2 mM 5-HT (1000-fold excess) was used. Cells grown in Lab-Tek chambers (Nunc, Denmark) were observed with a Zeiss LSM 510 Meta NLO confocal microscope (Jena, Germany). The imaging was performed with 63×, 1.4 NA, oil immersion objective. Compound 6 was excited at 561 nm with DPSS laser, and emission was collected using a bandpass filter at 575-630 nm.
