The operational stability of photo- and electroactive molecules is of prime importance. However, mechanisms by which the molecules degrade have yet been fully understood. We employ synthetic, steady-state and time-resolved spectroscopic, electrochemical, and quantum chemical techniques to establish factors that control the intrinsic stability of molecules. The biggest merit of photons is their tunable and high energies. To utilize the photon energy for synthetic purposes, it is imperative to develop catalysts with strong photo-reducing and –oxidizing power. We focus on unconventional molecular catalysts, such as radical ions and low-valent metal complexes, for activating redox-resistant substrates. Primary interests are placed on understanding catalysis mechanisms, and developing organic transformation protocols. Any biological processes can be photocontrolled. It is our prime research interest to develop molecular probes that can selectively detect biological species that are intimately involved in signal transmission in the human body. Further, we are also interested in photo(pro)drugs for photomodulation of neuronal and cellular signaling. There is increasing demands for photolithographic methods amenable to producing high throughput production of semiconductors. We initiated our research to develop photoresist materials for extreme ultraviolet (EUV) lithography. YouLab focus on organic molecular and polymeric materials. These materials offer unique advantages for creating functions. The structure of organic molecules and polymers can be modified over a broad range through synthetic techniques. Their syntheses are cost-effective, and enable fine tuning of their electronic and photonic properties. While the organic molecules and polymers serve as substrates for constr
