Structure of Fe-Phthalocyanine encapsulated inside SWCNT
FePc@SWCNT are peapods-like nanostructures composed Fe-phthalocyanine encapsulated inside Single-Walled Carbon Nanotube. This metallo-organic macrocycle (FePc) molecule exhibits not only optical but also structure depending magnetic properties. Through confinement inside the holow cavity of carbon nanotube, 1D chains of these molecules are created, with new confomationnal order and that are thus expected to exhibit specific properties (optical, magnetic). Preliminary XRD experiment have proven that FePc@SWCNT are filled with the guest molecules but also show a signature of confined 1D phase. We now aim at performing high resolution neutron diffraction (D16 instrument) on FePc@SWCNT in the range 2-320K, in order to fully identify the 1D phase, possible order/disorder transitions, and the associated magnetic properties.
