An atom or group whose presence is responsible for the color of a compound.
- ‘Benzene compounds with which chromophores are combined are known as chromogens.’
- ‘A summary statement of possible differences between the photochemistry of simple organic compounds and protein-bound chromophores appears appropriate here.’
- ‘Some other dye systems are based on the chromophores triphenylmethane, xanthene, anthroquinone, indigo, and phthalocyanine.’
- ‘Fading occurs when any chemical process breaks the sequence of conjugated double bonds constituting the chromophore - the dye moiety that imparts colour.’
- ‘While researchers have discovered all colored compounds do indeed contain one or more chromophores, not all chromophore containing compounds are colored.’
