| Research Abstract |
In order to develop a new fluorescent material' s platform in which fluorescent molecules can be easily dispersed anisotropically and densely, we prepared crystals of bile acid derivatives including various fluorescent dyes in the lipophilic channel spaces, and investigated their emission properties. As the results, it is revealed that dye molecules align densely in the channels without strong perturbation. Because of the arrangements, the inclusion crystals achieved high fluorescence quantum yields and blue-shifted spectra with narrower half width compared with the naked dye' s crystals.
