“…Among layered compounds with a van der Waals gap metal oxyhalides have been widely used as host lattices. [21][22][23][24][25][26][27] Intercalation enables confining guest molecules or polymer chains in a well-defined environment. The resulting intercalation hybrids often exhibit novel magnetic and electronic properties.…”

High-pressure behavior of FeOCl

A pressure-induced phase transition of FeOCl is discovered to occur at P c = 15 ± 1 GPa. It is preceded by extremely anisotropic lattice compression, which is explained by a gradual collapse of the van der Waals gap between the chlorine atoms on the borders of the slabs of this layered compound. Single-crystal x-ray diffraction in a diamond anvil cell is used to show that the high-pressure phase can be described as a fourfold superstructure with monoclinic lattice distortion, described by a 4a × 1b × 2c supercell with space group B2 1 /m (b unique). The high-pressure crystal structures have been used to uncover the mechanism of the phase transition, as the formation of alternating regions of increased packing density of chlorine atoms within a single layer and regions of interpenetrating layers. Raman and Mössbauer spectroscopies indicate that the phase transition is not related to electronic effects or magnetic order.

“…Indeed the conductivity is about three orders of magnitude lower than that reported previously for polypyrrole in the interlamellar spaces of Fe III OCl. [49] Another way in which a conducting chain could be enclosed in a coordination environment is if the environment is bonded to the chain, i.e., it forms the ligand shell of the chain. Square planar d 8 metal complexes which stack with either direct M± M contacts or via halide bridges, have been known for many years.…”

Conjugated polymers have an enormous range of potential applications, and recent work shows how many of these can be realized practically. Encapsulation can offer advantages in terms of separating polymer chains to inhibit interchain effects, improving the mechanical, thermal, and chemical stabilities of the assemblies, and possibly allowing individual molecular wires to be addressed. The Figure shows a schematic representation of a polyrotaxane, i.e., a polymer threaded into a host tube and held in place by end caps.

“…The integration of a nanostructured transition metal oxide into a conducting polymer matrix provides an effective way to harness the electrochemical activity of nanosized oxide clusters. By anchoring the transition metal oxides into conducting polymers, the reversible redox chemistry of the soluble polyoxometalate clusters can be combined with that of the conducting polymer to facilitate energy storage applications [14][15][16][17][18][19]. The results of a recent study reported that nano sized BaMnO3 is an excellent ceramic material which has high specific capacitance value and high rate of discharge [20].…”

The electro active inorganic-organic nanohybrid material Polyaniline-BaMnO3 has been synthesized by the surfactant assisted chemical polymerization reaction of aniline with nanocrystalline BaMnO3. Electrochemical studies have been performed using cyclic voltammetry and galvanostatic charge-discharge measurements.The enhanced electrode performance originates from the synergistic effect of PANI and BaMnO3. The hybrid delivers very high specific capacitance of 560.5 Fg -1 , energy density of 32.01 whkg -1 and power density of 400 wkg -1 , respectively. The hybrid also exhibits very high stability and excellent cycling performance with less than 5% capacity loss over 500 cycles.
