Charge transfer potentials pure systems

Comparison of the spectral response and of the power efficiency of these first conjugated polymer/fullerene bilayer devices with single layer pure conjugated polymer devices showed that the large potential of the photoinduced charge transfer of a donor-acceptor system was not fully exploited in the bilayers. The devices still suffer from antibatic behavior as well as from a low power conversion efficiency. However, the diode behavior, i.e. the rectification of these devices, was excellent. 

The interaction of nondegenerate molecular or charge-transfer states is insufficient to describe the stability of photoassociation products of molecules with different electronic energy levels, ionization potentials, and electron affinities. On the other hand, treatments26-26 of the exciplex as a pure charge-transfer state afford a quantitative description of the shift in fluorescence peak with solvent polarity and with electron affinity of the (fluorescent) donor in the same quencher-solvent system (Eq. 13) moreover, estimated values for the dipole moment of the emitting species (Table VI) confirm its pronounced charge-transfer character. 

The charge transfer in the first reaction is likely to occur because the ionization potential of water (12.6 eV) is lower than that of nitrogen (15.6 eV). When an APCI-MS system is mn with pure water as mobile phase, a series of protonated water clusters [(HjO) + H] can be observed in the low m/z region with the cluster ion with n=4 being especially abundant due to the magic numbers determining the stability of such clusters (Figure 6.4). If APCI-MS is done in...
