Photoinduced Processes

The organizational effect induced by noncovalent interactions such as hydrogen-bonding (H-B) and metal ion complexation on photoinduced processes is discussed. These include the intermolecular photodimerization of cinnamates, which is shown to occur under topochemical control within the supramolecular assemblies, and the intramolecular photodimerization of a bis-anthracene receptor where photoregulation of the recognition event is achieved. Progress in using supramolecular interactions toward the preparation of assemblies promoting charge separation and charge transport in all-organic photovoltaic devices rests on the preparation of materials that are adapted to the requirements of solid-state devices.

Blend Ratios

Classical molecular dynamics simulations and statistical thermodynamics are used to investigate the miscibility of blends of the conjugated polymer poly(3-hexylthiophene) (P3HT) and fullerene C60 for blend ratios typically used in organic photovoltaic devices over a range of temperatures. Depending on which of two slightly different simulation force fields is used, the calculations suggest that amorphous P3HT/fullerene blends are either miscible or immisicble under typical processing conditions. The former result is consistent with recent experiments and suggests that experimentally observed nano-scale phase separation is driven by polymer or fullerene crystallisation. But the inconsistency between the different force fields indicates that these blends are close to phase coexistence between the separated and homogeneously mixed phases and suggests that care must be taken in interpreting simulation data on P3HT/fullerene blends. These findings have implications for organic photovoltaics, in which the microstructure of conjugated-polymer/fullerene blends plays a crucial role in device performance.
