Electron Transfer System

Density functional theory (DFT) calculations, including electron correlation, were carried out on the N2 + N2+ electron transfer system. Six geometries of the precursor complex were assumed and their stabilities were calculated and compared. The activation energy, the electronic transmission factor, and the electronic coupling matrix element in the electron transfer process were also calculated. The electronic transmission factor for this system was far less than unity (ca. 0.006~0.09); thus, the electron transfer reaction was considered to be diabatic in nature. Therefore, the electron transfer rate for the selected structures was calculated using semiclassical and quantum-mechanical theories. The calculated values were compared with each other and were in good agreement with the experimental value.Key words: N2 + N2+ electron transfer reaction, semiclassical and quantum-mechanical theories, electronic transmission factor, electronic coupling matrix element, B3LYP.

The nature of electron transfer through intermolecular tunnel junctions has been studied. Intermolecular junctions feature non-hydrogen and hydrogen bonded interactions and are defined by the end groups of pairs of functionalized conjugated alkenes. We compared the distant dependent electron transfer from donor to acceptor group attached to the other sides of those functionalized conjugated alkenes. Study shows electron transfer coupling matrix element for these intermolecular junctions decays exponentially as a function of junction separation and quite substantial in energetically favourable hydrogen bonded intermolecular junctions.

Good Agreement

Theoretically calculated mobility has revealed that BDT is a hole transfer material, which is in good agreement with experimental investigations. The BDT, NHBDT, and OBDT are predicted to be hole transfer materials in the C2/c space group. Comparatively, hole mobility of BHBDT is 7 times while electron mobility is 20 times higher than the BDT. The packing effect for BDT and designed crystals was investigated by various space groups. Generally, mobility increases in BDT and its analogues by changing the packing from space group C2/c to space groups P1 or . In the designed ambipolar material, BHBDT hole mobility has been predicted 0.774 and 3.460 cm2 Vs–1 in space groups P1 and , which is 10 times and 48 times higher than BDT (0.075 and 0.072 cm2 Vs–1 in space groups P1 and ), respectively. Moreover, the BDT behaves as an electron transfer material by changing the packing from the C2/c space group to P1 and .
