Definition

1. Noun:
   • The chemical group that gives color to a molecule: A chromophore is the specific part or grouping of atoms within a molecule that is responsible for its color by absorbing light at certain wavelengths.

Usage Examples

• Noun:
  • The dye's vibrant blue color is due to a complex organic chromophore.
  • Scientists modified the chromophore to alter the pigment's properties.
  • Understanding the chromophore is key to developing new optical materials.

Advanced Usage

• "Chromophore bleaching": The process where a chromophore loses its ability to absorb light, often due to chemical reaction or intense light exposure.
  • Prolonged exposure to sunlight caused chromophore bleaching in the fabric.
• "Chromophore-assisted light inactivation (CALI)": A research technique using light-activated chromophores to inactivate specific proteins.
  • The study utilized chromophore-assisted light inactivation to probe protein function.

Variants and Related Words

• Chromophoric (adj): Relating to or containing a chromophore.
  • The chromophoric region of the protein was identified.
• Chromophoric group: Another term for chromophore.
  • The molecule's color originates from its chromophoric group.

Synonyms

• Color-bearing group
• Colorant moiety (technical)

Related Concepts

• Auxochrome: A functional group that, when attached to a chromophore, alters the wavelength and intensity of absorption.
  • An auxochrome can shift the color produced by the core chromophore.
• Absorption band: The range of wavelengths of light absorbed by a chromophore.
  • The chromophore's absorption band is in the visible spectrum.
