Transition energies (E(op)) of the nitrogen-centered pi,pi absorption of tetraalkylhydrazine radical cations are quite sensitive to twist at the NN bond, nitrogen pyramidality, and mixing of the sigma orbitals with the pi system. Thirty-one examples for which E(op) varies from 63 to 107.5 kcal/mol are discussed with the aid of calculated values (E(calc)) for the 0,0 transition energy using simple (no configuration interaction) neutral-in-cation-geometry calculations on AM1-UHF geometry…

π-Bonded molecular wires: self-assembly of mixed-valence cation-radical stacks within the nanochannels formed by inert tetrakis[3,5-bis(trifluoromethyl)phenyl]borate anions

A series of mixed-valence cation-radical salts D(n+1) TFPBn, where D is a planar organic donor of about 0.7 to 0.9 nm wide and 1.1 to 1.3 nm long (e.g., tetramethyltetraselenafulvalene,

Nonequilibrium solvation energy by means of constrained equilibrium thermodynamics and its application to self-exchange electron transfer reactions.

It is shown that the inner reorganization energies of these self-exchange ET reactions are not very sensitive to compound size while the compound size has some effect on the solvent reorganization energy in acetonitrile.

Tetraalkylalkene vertical ionization potentials revisited

The vertical ionization potentials for three tetra-α-branched-alkyl-substituted alkenes (13–15) are reported, compared with literature data for other tetralkylalkenes, and the values discussed with

Intermolecular electron transfer reactivity determined from cross-rate studies.

Electron-transfer cross-reactions between neutral molecules and their radical cations spanning a wide range of structural type and intrinsic reactivity have been analyzed using classical Marcus theory and a significant steric effect on this overlap is observed for hydrazines with alkyl groups larger than methyl.
