Research Overview

Our research interests and activities are primarily in the areas of solid-state inorganic and inorganic-organic hybrid materials that possess interesting and useful properties. Our recent work focuses largely on the design, synthesis, characterization, modification and understanding the chemistry of new materials with improved and enhanced functionality that are potentially important for clean and renewable energy storage and conversion, including photovoltaics, solid-state lighting, thermoelectrics, gas storage and separation, catalysis and sensing.

Inorganic-Organic Hybrid Semiconductors: A New Class of Nanostructured Crystals with Interesting and Enhanced Properties

hybrid nanostructured crystalsHybrid materials that incorporate organic and inorganic components into a single crystal lattice often lead to modified and enhanced properties, as well as new phenomena and new functionality. Recently, we have developed an unprecedented class of hybrid nanostructured crystals (Fig. 1) that are comprised of sub-nanometer-sized semiconductor motifs (inorganic component) and mono- or di-amines (organic component). These materials show exceptionally strong structure-, rather than size-induced, quantum confinement effect (QCE), and such confinement can be systematically tuned by modifying the composition, crystal structure and dimensionality of the inorganic motifs.

single-material white-lightThe II-VI based hybrid structures process a number of enhanced properties and new features over their parent bulk semiconductors. These include very broad band-gap tunability and high absorption coefficients, all desirable for optoelectronic applications. They are highly flexible, and exhibit nearly zero and tunable thermal expansion behavior. They represent the first semiconductor bulk materials that are capable of generating direct white light and thus, are promising for use as a single-material white-light emitting source in light-emitting diodes (Fig. 2). The hybrid semiconductors also possess a very rich structural chemistry and exhibit interesting structure related thermal properties.

Microporous Metal Organic Frameworks: A New Type of Adsorbents for Gas Storage, Gas Separation, and Sensing

highly porous MMOF structure and its propertiesMicroporous metal organic frameworks (MMOFs) are currently under intensive investigation because of their rich structural chemistry and very interesting properties. As a subclass of MOFs these materials contain micropores (pore diameter less than 20Å) and demonstrate porosity associated multi-fold functionality that show great promise for applications in gas storage and separation, catalysis, guest- and/or pore-induced magnetization and sensing. Compared to other porous materials such as zeolites and carbon nanotubes, MMOFs demonstrate numerous desirable and improved features. Their crystal structures (for example, dimensionality, framework connectivity, and topology), compositions (e.g. the type and form of metals and ligands) and pore properties (e.g., pore size and shape, pore volume and the chemical functionality of the pore walls) can be deliberately and systematically tailored to enhance targeted properties and to achieve improved performance. Fig. 3 shows a highly porous MMOF structure and its properties.

Metal Chalcogenides: Inorganic solids as Electronic, Optical and Zeotype Materials

structures of metal selenides and telluridesEarly investigations on binary metal chalcogenides had led to the discoveries of many important properties, including superconductivity, charge-density wave phenomena, ferromagnetism and anti-ferromagnetism, phase transitions, and anisotropic electrical and optical behavior. Important technological applications in heterogeneous catalysts, reversible battery electrodes, high temperature lubricants, optical storage materials, solar cells, solid state lasers, and thermoelectrics have been implemented as the result of such discoveries. The past several decades have witnessed tremendous efforts devoted to the exploitation of soft, low temperature synthetic methods for preparation of new multi-component chalcogenides. These efforts have led to the discovery of many new ternary and quaternary phases with remarkably rich structures and interesting properties. One of the strategies is to use organic templates both as charge-compensating and structure-directing agents. This approach has proven to be very effective in generating porous chalcogenides. Employing secondary building-block approach in our solution-based reactions, along with the use of large organic template species, we have succeeded in synthesizing a number of open framework structures of metal selenides and tellurides containing large pores (Fig. 4). Interesting and promising phases mimic the properties of zeotype materials are anticipated from this research.
