The main research theme in our group is discovering new electronic properties in organic and hybrid materials. En route to this goal, we are primarily engaged in design and synthesis of novel pi-conjugated molecules and polymers, and study of their optical and electronic behavior. While development of fundamental understanding in this field is our long-term goal, the objects are often selected with a specific application(s) in mind. These applications include organic light-emitting diodes (OLEDs), field-effect transistors (OFETs) and photovoltaic solar cells (OPVs). Some of these devices are being fabricated in our own lab.
Although organic synthesis accounts for about 70% of our research activity, the essence of these efforts is "making" novel properties, not merely new molecules. Thus, we are actively involved in studying the effects of molecular structure on optoelectronic properties. For this, we employ a range of spectroscopic and electrochemical techniques, and some device characterization approaches. One more recent involvement of the group is in the area of molecular self-assembly where we are trying to explore non-covalent interactions between the molecules to modulate/refine the semiconducting properties of organic materials. An ultimate goal of this approach would be developing bottom-up approaches for fabrication of molecular nanoelectronic circuits ("molecular computer"). Some current research directions of the group, with examples of recent projects are given below:
