pigmentmediated
Pigment-mediated describes processes in which pigments act as mediators of chemical, electronic, or photochemical transformations. In these systems, pigments absorb light or participate in redox chemistry and enable energy transfer, electron transfer, or catalytic turnover that drives downstream reactions. The term covers natural biological pigments as well as synthetic or extracted pigment molecules used in research and technology.
In biology and medicine, pigment-mediated processes are central to photosynthesis, where chlorophyll and related pigments channel
In materials science and environmental chemistry, pigments act as light absorbers or sensitizers that facilitate electron
Mechanistically, pigment mediation can involve energy transfer (for example, Förster-type transfer), direct electron transfer, or photosensitized
