International audience; Photoactive pi-conjugated molecules (quaterthiophene and phthalocyanine) are eitherencapsulated into the hollow core of single-walled carbon nanotubes or noncovalently stacked attheir outer surface in order to elaborate hybrid nanosystems with new physical properties, providingpractical routes to fit different requirements for potential applications.We are interested inthe relationship between the structure and the optoelectronic properties. The structural propertiesare investigated mainly by x-ray diffraction and/or transmission electron microscopy and Ramanspectroscopy. We show that the supramolecular organizations of confined quaterthiophenesdepend on the nanocontainer size, whereas phthalocyanine encapsulation leads to the formationof a one-dimensional phase for which the angle between the molecule ring and the nanotube axisis close to 32 deg. Confined phthalocyanine molecules display Raman spectra hardly altered withrespect to the bulk phase, suggesting a rather weak interaction with the tubes. In contrast, thevibrational properties of the molecules stacked at the outer surface of tubes display importantmodifications. We assume a significant curvature of the phthalocyanine induced by the interactionwith the tube walls and a change of the central atom position within the molecular ring, ingood agreement with our density functional theory calculations. |
