Normalized absorption and fluorescence emission spectra of DCDHF-P-6, DCDHF-N-6, and DCDHF-A-6 in toluene. Absorption for DCDHF-N-6 is at long enough wavelengths for excitation at 514 or 532 nm, thus avoiding much of the cellular autofluorescence; DCDHF-A-6 can be excited at 532 or 594 nm. Note also the enhanced Stokes shift of DCDHF-A-6 (104 nm) and DCDHF-N-6 (53 nm) over that of DCDHF-P-6 (21 nm).
