Ordered mesoporous silicas as host for the incorporation and aggregation of octanuclear nickel( ii ) single-molecule magnets: a bottom-up approach to new magnetic nanocomposite materials

Emilio Pardo、Pedro Burguete、Rafael Ruiz‐García 等 8 位作者2006-01-01Journal of Materials Chemistry

Silica-based mesoporous materials have been employed as the support host for a suitably designed small octanuclear nickel(II) guest complex with a moderately anisotropic S = 4 ground spin state (D = −0.23 cm−1), which behaves as a single-molecule magnet at low temperature (TB = 3.0 K). Both unimodal MCM-41 and bimodal…

Supramolecular chirality of columnar mesophases consisting of H-bonded complexes of melamine and polycatenar benzoic acids

Luciana Álvarez、J. Barberá、Laura Puig 等 6 位作者2006-01-01Journal of Materials Chemistry

The present work describes a series of H-bonded complexes consisting of a melamine derivative and polycatenar acids that show columnar liquid crystalline behaviour. Chirality has been transferred from the molecular blocks (either the acids, A3* and A4*, or the melamine, T2*) to the columnar organization. Particular ef…
