Table of photophysical properties. is reported at peak absorption. Quantum yield ( ) is reported as the average value measured between 475 nm and 535 nm. Contrast is measured as the relative fluorescence signal change between bound and unbound states ( F / F ), when exciting at 561 nm and detecting fluorescence signal at 575 nm. Because of red shift in both absorption and emission, the value is dependent on both excitation and emission parameters (see also Extended Data Fig. 1e–h ). Abs max, wavelength of maximum absorption; Em max, wavelength of maximum emission.
