Provided is a composition which comprises two immiscible compounds and a compatibiliser, which stabilises the interface between two or more immiscible compounds. The compatibiliser improves the morphology of blends comprising the first and second compounds. The composition may be useful in the context of functional blends for optoelectronic applications, such as solar cells, organic light-emitting diodes (OLEDs) and organic photovoltaics (OPVs). Also provided is a process for the preparation of the composition and compounds for use therein.

substituted perylenediimides with SnO 2 and TiO 2 semiconductor nanoparticles were investigated by various spectroscopic techniques for photovoltaic applications. For this purpose, two symmetrical and one new unsymmetrical perylenediimides were synthesized and characterized by IR, NMR and Mass spectroscopy. Optical properties of all the three compounds were investigated. Ground state interactions between

suppressed by the steric hindrance of a corona of incompatible glycol tails around the molecule, a more straightforward photophysical interaction of Förster energy transfer between the PDI moieties and Pc core may be inferred. We consider these molecules as prototypical multichromophoric aggregates, giving delocalised states with considerable flexibility of design.

The synthesis of an ionic quaterrylenebis(dicarboximide) 1a, a long-wavelength absorbing mesogen, is described. When compared with its analogue 2a, an ionic perylenebis(dicarboximide), the aromatic protons of 1a exchange with deuterium of concentrated D2SO4 at a dramatically faster rate. In addition, stronger aggregation in aqueous media was observed for 1a.
