Theoretical study of photoinduced electron transfer from tetramethylethylene to tetracyanoethylene
متن کامل
Photochemical control of a highly efficient addition reaction between electron-rich alkynes and tetracyanoethylene.
The electron density of an alkyne moiety is enhanced by the photochromic ring closure of a diarylethene derivative, which allows the thermal addition reaction with a small π-acceptor, tetracyanoethylene, at room temperature.
متن کاملDerivation of ionization energy and electron affinity equations using chemical hardness and absolute electronegativity in isoelectronic series
Chemical hardness () and absolute electronegativity () have important applications in chemistry. Inthe conceptual Density Functional theory (DFT), these concepts has been associated with electronicenergy and the relationship with ionization energy (I) and electron affinity (A) of these concepts hasbeen given. In this study, graphical method was used in order to see the relationship with the ato...
