Organic groups functionalised mesoporous silicates

Abstract: Great interests have been imparted on organically modified mesoporous silica materials due to their high surface areas, uniform pore sizes and integrated functionality. Besides the inherent character of inorganic and organic components, the interactions between them should also be recognised for the synthesis, including organic-group loading, mesostructure and particle morphology, condensation, as well as organic-group distribution. To obtain long range ordered hybrid materials, several factors, such as relative hydrolysis and condensation rates of the inorganic and organic sources, chemical character such as hydrophobicity/hydrophilicity and acid/base of organic ligand as well as the surfactant category, should be surveyed. A concept of 'combinatorial synthesis' is introduced here for the cases of combining two or more functional units in a typical synthesis into a single one. The silica precursors in the preparation of periodic mesoporous organosilanes (PMOs) are the aggregation of inorganic and organic silicates. The assembly will lead to a unique distribution and high concentration of functional groups. Both the confinement within the mesopores and the pore surface nature will affect the accessibility to the active sites, and therefore, the adsorption and relative applications. These characters win them ample host-guest chemistry. They can seek the opportunities in the fields of catalysis, separation, electronic devices, biomedicines, nanomaterial fabrication, etc.

Self-assembled lamellar MoS2, SnS2 and SiO2 semiconducting polymer nanocomposites.

Abstract: Lamellar nanocomposites based on semiconducting polymers incorporated into layered inorganic matrices are prepared by the co-assembly of organic and inorganic precursors Semiconducting polymer-incorporated silica is prepared by introducing the semiconducting polymers into a tetrahydrofuran (THF)/water homogeneous sol solution containing silica precursor species and a surface-active agent Semiconducting polymer-incorporated MoS2 and SnS2 are prepared by Li intercalation into the inorganic compound, exfoliation and restack in the presence of the semiconducting polymer All lamellar nanocomposite films are organized in domains aligned parallel to the substrate surface plane The incorporated polymers maintain their semiconducting properties, as evident from their optical absorption and photoluminescence spectra The optoelectronic properties of the nanocomposites depend on the properties of both the inorganic host and the incorporated guest polymer as demonstrated by integrating the nanocomposite films into light-emitting diodes Devices based on polymer-incorporated silica and polymer-incorporated MoS2 show no diode behaviour and no light emission due to the insulating and metallic properties of the silica and MoS2 hosts In contrast, diode performance and electroluminescence are obtained from devices based on semiconducting polymer-incorporated semiconducting SnS2, demonstrating that judicious selection of the composite components in combination with the optimization of material synthesis conditions allows new hierarchical structures to be tailored for electronic and optoelectronic applications

Proton conductive composite membranes

Abstract: In this work we investigated the synthesis of composite organic and inorganic membranes for proton conduction. Particles derived from metal alkoxides (M(OR)n) sol-gel processes (Ti, Zr, W with phosphoric acid) were embedded in polymeric matrices of poly-vinyl alcohol, (3-glycidoxypropyl)-trimethoxysilane and ethylene glycol. The structure of the composite membranes was complex as several IR peaks were convoluted, indicating the assignment of several functional groups. However, the peaks assigned to OH groups reduced in intensity in the composite membranes, indicating that cross-linking of hydroxyl groups in the organic and inorganic phases of the membrane may have occurred. The particles allowed for re-arrangement of the polymer matrix, as crystallinity was reduced compared to a polymer blank membrane. The composite membrane process resulted in homogeneous dispersion of nanoparticles into the polymer film. Proton conduction of the inorganic phase was mainly dominated by titania. Binary mixtures of titania phosphate (sample name TiP) resulted in proton conduction of 7.15 ? 10−2 S.cm−1, one order of magnitude higher than zirconia phosphate (ZrP). The addition of Zr and W to TiP forming ternary or quaternary phases also led to lower proton conduction as compared to TiP. Similar trends were also observed for the composite membranes, though the TiP composite membrane proton conduction reduced after several hours of testing at 50?C, which was mainly attributed to acid leaching.
