Résumé

Novel [Fe(Rtrz)3](SO3CF3)2 based SCO nanomaterials were fabricated through the supramolecular gel strategy. By modifying the assembly conditions, surfactant or polymer-free SCO nanomaterial with different sizes and morphologies could be prepared. Furthermore, their spin crossover behavior was investigated by optical, magnetic and Mössbauer measurements. The spin transition features for the nano-sized materials presented room temperature transition with a hysteresis loop, which could mainly be attributed to the intermolecular van der Waals interactions of tris(dodecyloxy)-benzamide introduced on the structure of [Fe(Rtrz)3](SO3CF3)2.
