Wikipedia
A chromophore is the part of a molecule responsible for its color. The color arises when a molecule absorbs certain wavelengths of visible light and transmits or reflects others. The chromophore is a region in the molecule where the energy difference between two different molecular orbitals falls within the range of the visible spectrum. Visible light that hits the chromophore can thus be absorbed by exciting an electron from its ground state into an excited state.
In biological molecules that serve to capture or detect light energy, the chromophore is the moiety that causes a conformational change of the molecule when hit by light.
Usage examples of "chromophore".
Light entering the eye brings about a change in the chromophore in the first thousandth of a second, and after that the rest of the changes are automatic, a causal chain that results in the experiencing of a vision of some sort.
This bacterial protein, commonly found in salt marshes, included a segment known as a chromophore, which changed its properties when exposed to light.
The absorbed energy initiated a branching reaction, a sequential one photon architecture-a set of wavelength keys fitted across the darkness into a self-repairing chromophore lock originally built of bacterial protein.
