electron-donor-acceptor complex
61Unimolecular rectifier — Single organic molecules can function as rectifiers (one way conductors) of electric current. This was first proposed in 1974 by Arieh (later Ari) Aviram, then at IBM, and Mark Ratner, then at New York University; their publication was the first… …
62Copper in health — Normal absorption and distribution of copper. Cu = copper, CP = ceruloplasmin, green = ATP7B carrying copper. Copper is an essential trace element that is vital to the health of all living things (humans, plants, animals, and microorganisms). In… …
63Catenane — [ thumbnail|230px|Schematic animation of the template directed synthesis of the bis bipyridinium cyclophane / paraphanylene crown ether [2] catenane described in the text.] A catenane is a mechanically interlocked molecular architecture… …
64coordination compound — Chem. complex (def. 10). Also called coordination complex. * * * ▪ chemistry Introduction any of a class of substances with chemical structures in which a central metal atom is surrounded by nonmetal atoms or groups of atoms, called ligands… …
65Förster resonance energy transfer — (abbreviated FRET), also known as Fluoresence resonance energy transfer or resonance energy transfer (RET), describes an energy transfer mechanism between two chromophores. A donor chromophore in its excited state can transfer energy by a… …
66Light-dependent reaction — The initial stage of the photosynthetic system is the light dependent reaction, which converts solar energy into potential energy. The light dependent reaction produces oxygen gas and converts ADP and NADP+ intothe energy carriers ATP and… …

68Hydrogen bond — A hydrogen bond results from a dipole dipole force between an electronegative atom and a hydrogen atom bonded to nitrogen, oxygen or fluorine (thus the name hydrogen bond , which must not be confused with a covalent bond to hydrogen). The energy… …
69Chemical glycosylation — A chemical glycosylation reaction involves the coupling of a sugar to a glycosyl acceptor forming a glycoside.[1][2][3] If the acceptor is another sugar, the product is an oligosaccharide. The reaction involves coupling a glycosyl donor to a… …
70Metal–ligand multiple bond — In Chemistry, a metal–ligand multiple bond describes the interaction of certain ligands with a metal with a bond order greater than one.[1] Coordination complexes featuring multiply bonded ligands are of both scholarly and practical interest.… …
