An oligophenylenevinylene (OPV) derivative substituted with two fullerene subunits has been prepared starting from a fullerene carboxylic acid derivative and an OPV heptamer bearing two alcohol functions. Photophysical investigations have revealed the occurrence of intramolecular photoinduced energy- and electron-transfer processes in this hybrid compound. Georg Thieme Verlag Stuttgart.

Assemblies of four oligophenylenevinylene moieties arising from a calix[4]arene core, i.e., calix[4]-oligophenylenevinylenes, have been prepared by Heck-type cross-coupling reactions of styrene derivatives with a tetraiodinated cone-calix[4]arene precursor. Photophysical studies in solution have revealed that there are electronic ground state interactions between the covalently bonded OPV moieties. The absorption spectra of the calix[4]oligophenylenevinylenes are significantly different from those obtained by summing the spectra of four model units and their emission is red-shifted when compared to the corresponding model compounds. Electrochemical studies have shown that the redox processes of the four OPV subunits do not take place at the same potentials indicating also a strong electronic interaction among them in the calix[4]oligophenylenevinylenes.
