Materials Chemistry


materialsThe materials chemistry program at UCR focuses on the design, synthesis and characterization of new functional materials, understanding the fundamental chemical principles governing their fabrication, investigating their properties, and exploring their unique applications. Students in the materials chemistry program will be provided with opportunities to develop interdisciplinary research expertise via collaborations in engineering, physics and biological sciences. At UCR, the research in materials chemistry covers a wide range of materials including molecular materials (Bardeen, Bocian, Marsella, Reed), polymers (Cheng), solid state materials (Feng, Haddon, Ozkan, Yin), colloidal materials (Tang, Yin), and composite/hybrid materials (Haddon, Tang, Yin). These materials are processed at different length scales spanning from the molecular level to nanometer and micrometer sizes, often in the form of nano- or microcrystals, thin films, and porous structures. Significant efforts have been focused on the exploration of niche applications for these materials in a variety of areas, including sensors and actuators (Bardeen, Bartels, Cheng), electronic and photonic devices (Bartels, Bocian, Haddon, Tang, Yin), as well as catalysis and energy applications (Bardeen, Feng, Ozkan, Yin, Zaera). A number of groups are also actively developing cutting edge characterization tools to study various aspects of the formation processes and properties of the new materials (Bartels, Zaera, Zhang). With unique computational expertise, the Beran group aims to predict the chemical behaviors of gases and solid state materials through calculations. Many faculty members working in materials chemistry have joint positions in the Materials Science and Engineering Program at the Bourns College of Engineering. The Center for Nanoscale Science and Engineering, furnished with a state-of-the-art nanofabrication research facility, is headquartered in the Chemistry Department.

Faculty Research Descriptions:

Christopher Bardeen
The Bardeen group seeks to develop new organic materials that can transform light into electrical or mechanical energy. By controlling the size and shape of crystals composed of conjugated organic molecules, we can affect their mechanical and electronic properties. These crystals can be used as components in applications like organic solar cells and nanoscale photomechanical actuators.

Ludwig Bartels
The Bartels group synthesizes metal dichalcogenide materials such as MoS2, MoSe2, WS2 etc. We characterize their electronic, optic, (photo-)catalytic and chemical behavior using a broad range of techniques. Funding of this effort is provided by the Semiconductor Research Corporation, NSF and other sources.

Gregory Beran
Quantum chemistry in liquids and solids: The Beran group uses computational quantum chemistry to predict chemical behavior in the gas and condensed phases. Recent work has focused on predicting molecular crystal structures and properties, mechanisms in heterogenous catalysis, and the interpretation of various spectroscopic experiments. We develop the new theoretical algorithms that make high-quality and robust predictions feasible in these complex systems.

David Bocian
Molecular Materials for Photonics and Electronics. The Bocian group is engaged in a variety of studies that broadly encompass physical, biological, and materials chemistry.  The types of systems/areas being investigating include heme and photosynthetic proteins, synthetic light-harvesting arrays, molecular photonic devices, electrically addressable molecular-based memories, and molecules for light-mediated diagnostics, imaging, and therapy.

Quan Jason Cheng
The materials chemistry research in the Cheng group focuses on supramolecular assemblies of conjugated lipid molecules and electrospun nanofibers. Emphasis is placed on exploration of novel optical properties of the materials for biosensing application. We are particularly interested in polydiacetylenes (PDA) and similar conjugated systems, and polymer/metal oxide nanofibers capable of FRET detection and enhanced electron transfer.

Boniface Fokwa
The Fokwa research group is interested in novel inorganic solids derived from the combination of main group elements and metals (mainly transition metals). Much emphasis lies on the elucidation of the crystal and electronic structures as well as structure-bonding-property correlations of such new compounds, thus enabling their potential applications as materials for energy related technologies (magnetic, magnetocaloric, superconducting and spintronic materials) as well as refractory materials (hard and superhard materials) and catalysts.

Hybrid Nanomaterials. Research in Tang group will utilize supramolecular & colloidal chemistry, as well as single particle spectroscopy, to investigate the surfaces and self-assembly of nanocrystals. We seek to further the understanding of the organic-inorganic interface that defines the properties of nanocrystals, and to address the challenges in 3D nanoparticle self-assembly, to make, for example, metamaterials active at visible wavelengths. Operating at the interface of chemistry, applied physics and materials science, we will design, synthesize and characterize hybrid materials with novel optoelectronic, photonic and catalytic applications.
