  text: Photoinduced electron transfer (PET), which causes pH-dependent quenching
    of fluorescent dyes, is more effectively introduced by phenolic groups than by
    amino groups which have been much more commonly used so far. That is demonstrated
    by fluorescence measurements involving several classes of fluorophores. Electrochemical
    measurements show that PET in several amino-modified dyes is thermodynamically
    favorable, even though it was not experimentally found, underlining the importance
    of kinetic aspects to the process. Consequently, the attachment of phenolic groups
    allows for fast and simple preparation of a wide selection of fluorescent pH-probes
    with tailor-made spectral properties, sensitive ranges, and individual advantages,
    so that a large number of applications can be realized. Fluorophores carrying
    phenolic groups may also be used for sensing analytes other than pH or molecular
    switching and signaling.
