In photosynthesis and organic photovoltaics, pigment molecules convert light into electrical charge. A team of chemists have now produced an unusual organic pigment, which is “switched on” by an electrical charge to become a potent dye that absorbs light in the near-infrared range. The team’s study, published in the journal Angewandte Chemie, suggests potential applications in systems for electrophysical materials research, photovoltaics, and sensor technology.
