摘要: Double-decker phthalocyanine lanthanide complexes are single molecule magnets (SMMs) presenting a thermally activated magnetic relaxation with relatively high effective barriers. For this reason they potential candidates as components for data storage and spintronic devices. One of the disadvantages these compounds is their redox instability: oxidized or reduced in presence mild oxidizing reducing agents. To solve issue, we designed, prepared characterized new double-decker based SMMs bearing electron withdrawing groups therefore an increased stability. In present article, synthesis characterization novel presented demonstrate how behavior virtually identical to that parent unsubstituted compounds.
