- 中文摘要: The emission spectra of quinidine and quinidine sulfate doped in sol-gels (tetraethoxysiliane system) have been measured during the sol-gel transformation. Shifts in the emission spectra from 370 nm to 435 nm were observed in both molecules as the system changed from sol stage to dried glass over a period of two weeks. These shifts are attributed to the conformational changes of the doped molecules. In addition, the process of the signal changes was observed by an emerging new band at ~435 nm with a concomitant decline of the original band at 370 nm during the sol-gel transformation. These results indicate that the conformational changes induced by the sol-gel transformation are accomplished in one step instead of several intermediate states.
