Mixed Valence Materials: Prussian Blue Analogues of Reduced Dimensionality (Small 16/2012)

The cover image shows an artistic view of the “on surface” synthesis of low-dimensional Prussian Blue Analogues (PBAs) on a layered aluminosilicate clay mineral. The network of spheres illustrates the innovative bi-dimensional arrangement of PBAs as synthesized in a self-limited cation exchange reaction on the clay surface. Well-packed clay platelet monolayers (visible in the blue background), deposited by a Langmuir–Schaefer approach, are used here as templates. This low-dimensional assembly preserves a high Tc of ∼80 K and gives rise to a new magnetic behavior between superparamagnetic and spin-glass properties.
