Chromophore vs. Fluorophore

Chromophorenoun

(chemistry) that part of the molecule of a dye responsible for its colour

Chromophorenoun

(chemistry) (more generally) the group of atoms in a molecule in which the electronic transition responsible for a given spectral band is located

Chromophorenoun

Any chemical group or residue (as NO2; N2; or O2) which imparts some decided color to the compound of which it is an ingredient.

Chromophorenoun

the chemical group that gives color to a molecule

Chromophore

A chromophore is the part of a molecule responsible for its color. The color that is seen by our eyes is the one not absorbed by the reflecting object within a certain wavelength spectrum of visible light.

Fluorophorenoun

(biochemistry) A molecule or functional group which is capable of fluorescence.

Fluorophorenoun

Any group of atoms whose presence in a molecule causes the molecule to be fluorescent.

Fluorophorenoun

Any fluorescent compound.

Fluorophore

A fluorophore (or fluorochrome, similarly to a chromophore) is a fluorescent chemical compound that can re-emit light upon light excitation. 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).
