| Research Abstract |
We have developed novel fast photochromic molecules, which show instantaneous coloration upon exposure to UV light and rapid fading in the dark. Fast thermal-bleaching kinetics enable a solution color change only where it is irradiated with UV light, because the thermal-bleaching rate is much faster than the diffusion rate of the colored species at room temperature. Photochromic materials showing such intense photocoloration and fast thermal-bleaching performance are promising materials for prospective fast light-modulator applications.
