(redirected from Chromophores)

   Also found in: Dictionary/thesaurus, Encyclopedia, Wikipedia 0.01 sec.
chromophore /chro·mo·phore/ (kro´mo-for) any chemical group whose presence gives a decided color to a compound and which unites with certain other groups (auxochromes) to form dyes.
chro·mo·phore (krm-fôr) or chro·mat·o·phore (kr-mt-)
n.
A chemical group capable of selective light absorption resulting in coloration of certain organic compounds. Also called color radical.

radical [rad´ĭ-kal]
1. thorough or sweeping; directed to the cause or root of a morbid process.
2. a group of atoms that enters into and goes out of chemical combination without change and that forms one of the fundamental constituents of a molecule.
color radical chromophore.
free radical a radical that carries an unpaired electron; such radicals are extremely reactive, with a very short half-life.
oxygen radical a toxic metabolite of oxygen, such as superoxide or singlet oxygen, capable of damaging microorganisms and normal tissues.

chromophore

After exposure to light, key components of pigments called chromophores can leave the cells and travel to the nearby pigment epithelium near the retina.
Organic nonlinear optical (NLO) active chromophores are considered to be most important materials, for their wide applications in photonics, which is typically a polarizable molecule consisting of a [pi]-conjugated system with a donor and acceptor group (4).
Other subjects explored include hydrogen bonding effects on the photochemistry of chromophores in solution, photochemical generation of silicon-centered radicals and their reactions, and photochemical processes at the air-water interface of atmospheric droplets.
