A variety of functional materials are used in electronic products such as televisions, computers, and cell phones, and recently, electronic products using organic materials such as organic EL televisions are becoming more familiar. In our laboratory, we are focusing on metal complexes, and are developing new metal complexes that can be applied to electronic devices, such as thin-film solar cells, field-effect transistors (FETs), and organic light emitting diodes (OLEDs). We are also developing new metal complexes in order to apply them to electronic devices. We are also conducting research to improve the efficiency of organic thin-film solar cells.
