Electron affinity value was found positive which indicate that the synthesized molecule might participate in charge transfer reactions.
Other relevant parameters included the ionization potential (I), electronegativity [chi], electron affinity (A), hardness ([eta]), and affinity index ([omega]).
Selective detection of TNP is very difficult as it has strong electron affinity [13].
Ionization potential (IP) and electron affinity (EA) are important data for measuring the injection ability of holes and electrons [51-53].
The step-by-step substitution of the functional group on the polypyridyl ligand allows analysis with essentially a single variable, changing the electron affinity of the terminal group on the polypyridyl ligand.
The electron affinity (A) and ionization potential (I) can affect the energy barrier of electrons.
The ionization potential (IP) and electron affinity (EA) is well-defined properties that can be calculated by the DFT to estimate the energy barrier for the injection of both holes and electrons.
The calculation involved the method of selecting the parameters such as the exponents of STO's, the valence orbital ionization potentials, the electron affinity, the electronegativity, the Slater's electrostatic parameters and the bonding parameters etc., and recommended most suitable values for these parameters.
On the contrary, monobromination improves the electron affinity of the [T.sub.1] product, with the degree of improvement being controlled by the position of monobromination.
"So once we put these two materials together, electrons move from one to another based on their different electron affinity," Wang said.
Polarization-dependent electron affinity of LiNbO3 surfaces.
In the corona, the interaction between free atoms or ions with condensed matter results in the production of highly ionized species, like FeXXV [23,24], since condensed matter has the ability to maintain a higher electron affinity than a free atom.
