Abstract
Hybrid magnetic multilayers have been synthesized by means of intercalation of [5,10,15,20-tetrakis(4-sulfonatophenyl)porphyrinato]cobalt(II) (CoTPPS) complex in the interlayer space of a NiIIFeIII layered double hydroxide (LDH), through anion-exchange reaction. A sebacate ( –OOC-(CH2)8-COO–) intercalated NiFe-LDH have been used as precursor, facilitating the anion exchange reaction, thus permitting the inclusion of a paramagnetic macrocycle inside the ferrimagnetic NiFe-LDH layers. The material has been characterized by XRD, FT-IR, SEM, SQUID and ESR. The Tc for the hybrid NiFe-CoTPPS, ca. 11-12 K, is very close to that shown by the precursor, despite that the intercalation of the complex promotes an expansion in the basal space from 15.4 to 22.4 Å.
