单词	chromophore
释义	chromophore /ˈkrəʊməfɔː / noun Chemistry An atom or group whose presence is responsible for the colour of a compound.While researchers have discovered all colored compounds do indeed contain one or more chromophores, not all chromophore containing compounds are colored.... Fading occurs when any chemical process breaks the sequence of conjugated double bonds constituting the chromophore - the dye moiety that imparts colour. Benzene compounds with which chromophores are combined are known as chromogens. Derivatives chromophoric adjective ... Such heterogeneous systems are generally characterized by the confinement of groups of chromophoric molecules to micron- or submicron-sized structures, which are dispersed in a buffered, partly aqueous medium. As the chromophoric part of the molecule is inserted deeper in the membrane, singlet oxygen is produced by photosensitization at a greater depth. Here, internal protonation processes between the chromophoric group and the proton binding site close to the chromophoric group were assumed.
