Thus, the PET occurs from the electron donor o-phenylenediamine to the naphthalimide core (a-PET process). As a result, the fluorophore will be in the off state.

We have focused our research mainly on developing fluorescent photoinduced electron transfer (PET) sensors based on the fluorophore-spacer-anion receptor principle using several anthracene (emitting in the blue) and 1,8-naphthalimide (emitting in the green) fluorophores, with the aim of targeting biologically and industrially relevant anions such as acetates, phosphate and amino acids, as well as halides such as fluoride.

Known as chromophores, different wavelengths of light are absorbed by fluorophores, creating the light that is visible. This is essentially a region in which the orbits of two different molecules' electrons are located. The advantage of contact quenching over conventional FRET- or PeT- based systems is that it can be completely abolished by disrupting the complex between fluorophore and quencher upon binding of the aptamer to the fluorophore, while FRET or PeT quenching could not be fully suppressed. Fluorescence imaging is an attractive method for monitoring neuronal activity. A key challenge for optically monitoring voltage is development of sensors that can give large and fast responses to changes in transmembrane potential. We now present fluorescent sensors that detect voltage changes in neurons by modulation of photo-induced electron transfer (PeT) from an electron donor through a 2019-01-12 · Fluorophores typically contain several combined aromatic groups, or planar or cyclic molecules with several π bonds.Fluorophores are sometimes used alone, as a tracer in fluids, as a dye for staining of certain structures, as a substrate of enzymes, or as a probe or indicator (when its fluorescence is affected by environmental aspects such as polarity or ions). The mechanism of PET-based fluorescence ion sensors can be described in terms of the molecular orbital (MO) energies and redox potentials of the ionophore and fluorophore [19, 20].

Fluorophores are metabolized in vivo, as are other injectates.
