We develop new organic and inorganic molecules and materials with interesting properties that may find applications in electronics, photonics, catalysis, and other areas. We make the materials, characterize them, and study their properties, often in collaborations. We develop diverse materials - solid-state structures, polymers, gels, glasses, liquid crystals, etc. - to address interesting scientific and engineering problems. Some of our projects are aimed a combating environmental problems or improving alternative energy applications, such as solar energy conversion and hydrogen fuel cells.
Students make new molecules and materials, and study them by a large variety of techniques – electron microscopy, thermal analysis, NMR spectroscopy, IR / Raman spectroscopy, UV-vis / fluorescence spectroscopy, mass spectrometry, light scattering, X-ray crystallography, gas adsorption, calorimetry, polarizing optical microscopy, circular dichroism spectroscopy, electrochemistry, etc. We are also part of an innovative training program in nanomaterials at UBC, NanoMat.
Below are examples of projects in progress or recently completed:
1. Mesoporous materials. We are creating new mesoporous materials for applications in optics, supercapacitor electrodes, and catalysis.
2. Supramolecular chemistry with macrocycles. We are working on the synthesis and self-assembly of new macrocycles, such as the macrocycles shown below:
3. Molecules with interesting shapes and properties.
4. Self-assembled structures, including gels.
