Beyond Silica: Nonoxidic Mesostructured Materials

Abstract

Recent advances in the design and synthesis of mesostructured and mesoporous materials with nonoxide frameworks are reviewed. Chalcogenides comprise the most important class, and all possible pore arrangements known for silica can be achieved in these materials. The special molecular chemistry that leads to organized nonoxidic mesostructures that have a variety of compositions, pore sizes, and semiconductor bandgaps is presented. Also reviewed are recent developments in mesoporous elements, such as metals and germanium. The goal in research on mesoporous semiconductors is to create materials scaffolds with new physical phenomena that derive from the combined characteristics of long‐range porosity and electronic and optical properties.

Polyoxotungstate-Surfactant Layered Crystal toward Conductive Inorganic-Organic Hybrid

“…POMs can add various physicochemical properties to the hybrids as inorganic components [12][13][14][15][16], while surfactants enable the control of layered structures as structure-directing organic components [17][18][19]. While there are many types of POM-surfactant hybrid [9][10][11][20][21][22][23][24][25], POM-surfactant single crystals are rare [26][27][28][29][30][31][32].…”

One-pot synthesis of amino functionalized mesoporous silica materials: using simulations to understand transitions between different structures

“…17 Mesostructured organic-inorganic hybrids are not restricted to silica based materials. Well ordered materials can be obtained using a variety of sources, including transition metal oxides, 18 nonoxidic materials 19 and hybrid organic-inorganic precursors.…”

White-light photoluminescence and photoactivation in cadmium sulfide embedded in mesoporous silicon dioxide templates studied by confocal laser scanning microscopy

“…Therefore, these arrangements are often referred to as ''quan-107 tum antidots'' [28,29]. Similar to QDs, it should be possible to tune 108 the band gap of quantum antidots to meet specific technological 109 demands [29]. Actually, some functionalities of QDs that depend 110 on the overall surface area (e.g., photocatalysis, photovoltaic activ-111 ity and electrochemical properties) would presumably be 112 enhanced in mesoporous quantum antidots [25,30].…”
