Hole Multiplexing in Quinone Derivative Photochemical Hole Burning Systems,
Abstract
We have been interested in PHB mechanism in the quinone derivatives. The substituent effects of the guest molecules are examined on the hole multiplexing 3, hole formation wavelength range and electric field effect 4. We especially intend to know how densely multiple holes can be formed by wavelength tuning and Stark tuning. First, the substituent effect on hole density and hole formation range in the wavelength dimension has been investigated. It has been proved to be important to select the proper substituents. Second, the Stark effect on the PHB reaction characteristics in the amorphous hosts has been investigated. Also in the quinone derivative systems, the Stark effect has been successfully observed. Five multiple holes in the electric field dimension have been produced at 4.2 K. The dipole moment difference Delta u between in the ground state and in the excited state of the guest molecule has been estimated by the spectral hole shift due to the applied electric field.
