The search for cleaner and more abundant sources of energy is one of the major scientific challenges of the 21st century. Owing to its privileged position as the central science, chemistry is bound to play a leading role in this quest. Within the search for new materials for organic photovoltaics, some of the work we have carried out concerning the supra-molecular chemistry of electron donor and acceptor molecules is presented.

<p class="03Abstract">Two merocyanine dyes containing a malononitrile or a ketone functional group as electron-acceptors, and a piperidine group as electron-donor were synthetized and crystallized as pigments. The electron-donor and -acceptor moieties are linked <em>via</em> an octahydroanthracene skeleton, forming an electronic push-pull molecular system. The crystal structure of the malononitrile compound was solved <em>ab initio</em> from X-ray powder diffraction data, complementing the reported structure of the ketone pigment. Both compounds show similar molecular structures in the solid state, yet with completely different crystal packing schemes. The crystal structures were analysed with inspecting the Hirshfeld surfaces. IR spectroscopy was applied to complement the crystallographic study. The absorption characteristics of both pigments emerge from the push-pull chemical structure, which was visualized by plotting the electrostatic potentials, calculated using molecular geometries as observed in the solid state. The solid state UV-vis spectra showed peak broadening and bathochromic spectral shift as compared to the spectra recorded in solution, depending on the polarity of the solvent molecules: The largest shifts of the spectra of solid state pigments were observed with respect to the spectra recorded in toluene solution, whether the smallest to those in ethanol. </p>
