| Summary: | 碩士 === 國立交通大學 === 應用化學系碩博士班 === 104 === In this study, we modified the lowerrim of the calix[4]arene by attaching distal pyrene unit as the fluorophore through the click chemistry of pyrene azides with 25, 27bispropargyl calix[4]arene. Based on the methods developed by Ms. YingJung Chen, we successfully synthesized the unique skeleton of calix[4]quinone and its derivatives 3336. Based on the results from UVVis spectroscopy and fluorescence spectrometry, we found that fluorescence emission intensity decreased, because more flexible structure will cause energy lost in the cases of 33; 34 possesses an efficient excimer formation and emission, and the fluorescent spectra changes observed upon addition of various metal ions show that 34 is selective for Cd2+ and Zn2+ over other metal ions; Owing to the low yield of 35, we didn’t investigate the allosteric effect of 35. In addition, compound 36 was found to change color when anion such as F-, AcO- and H2PO4- was added to its solution. Moreover, we further investigate the complexation models by using NMR titration spectroscopy.
