Abstract

Nanochannels of the metal–organic framework {Fe(pyrazine)[Ni(CN) 4 ]} were loaded by pyrrole molecules from the vapor phase. Subsequent oxidation using an iodine solution resulted in the formation of conductive polypyrrole chains within the porous host. The obtained composite materials were characterized by powder X-ray diffraction; specific surface area analysis; Mössbauer, dielectric, and vibrational [Raman and FTIR] spectroscopies; magnetic susceptibility; and electrical conductivity measurements. Remarkably, the bulk electrical conductivity of the composites is enhanced by up to 6 orders of magnitude, and the spin-crossover property is retained to a large extent. These results constitute a breakthrough, opening novel perspectives for the development of highly conductive, spin-crossover molecular materials.
