donor-acceptor bonding
1Donor number — In chemistry a donor number or DN is a qualitative measure of Lewis basicity. A donor number is defined as the negative enthalpy value for the 1:1 adduct formation between a Lewis base and the standard Lewis acid SbCl5 (antimony pentachloride),… …
2hydrogen bonding — Interaction involving a hydrogen atom located between a pair of other atoms having a high affinity for electrons; such a bond is weaker than an ionic bond or covalent bond but stronger than van der Waals forces. Hydrogen bonds can exist between… …
3organometallic compound — ▪ chemical compound Introduction any member of a class of substances containing at least one metal to carbon bond in which the carbon is part of an organic group. Organometallic compounds constitute a very large group of substances that have… …
4Acid dissociation constant — Acetic acid, a weak acid, donates a proton (hydrogen ion, high …
5cell — cell1 cell like, adj. /sel/, n. 1. a small room, as in a convent or prison. 2. any of various small compartments or bounded areas forming part of a whole. 3. a small group acting as a unit within a larger organization: a local cell of the… …
6Organic solar cell — An organic photovoltaic cell (OPVC) is a photovoltaic cell that uses organic electronics a branch of electronics that deals with conductive organic polymers or small organic molecules[1] for light absorption and charge transport. The plastic… …
7Kinetic isotope effect — The kinetic isotope effect (KIE) is the ratio of reaction rates of two different isotopically labeled molecules in a chemical reaction. It is also called isotope fractionation, although this term is somewhat broader in meaning. A KIE involving… …
8Liaisons Halogènes — Liaison halogène Il existe un monde parallèle à celui de la liaison hydrogène (HB), qui est celui de la liaison halogène (XB) qui s établit entre les atomes d halogènes électrodéficients (appauvris en densité électronique), facilement… …
9Carbon nanotubes in photovoltaics — Organic photovoltaic devices (OPVs) are fabricated from thin films of organic semiconductors, such as polymers and small molecule compounds, and are typically on the order of 100 nm thick. Because polymer based OPVs can be made using a coating… …
10Crystallographic defects in diamond — Synthetic diamonds of various colors grown by the high pressure high temperature technique, the diamond size is 2 mm …
