| Summary: | 碩士 === 國立臺灣科技大學 === 化學工程系 === 102 === Triptycene is a three-dimensional molecules, it can prevents the triptycene molecules from aggregating. In recent years, there are much researches in triptycene molecules, the scientists mixed triptycene with the liquid crystal, it can make the liquid crystal arrangement much orderly, or synthesized the triptycene polymer molecules to make the aggregation much weaker. These are the researches in materials. However, the study of the molecular triptycene derivatives is much less the former. So we decided to do the research in 1-4diaryltriptycene derivatives
This thesis discusses a series of 1,4-diaryl triptycene derivatives which have the symmetrical skeleton, we use various instruments to measure their absorption spectra of molecules, fluorescence spectroscopy, molecular theory model, and compare them to the literature which does not have the triptycene structure and discussed what will affect the photophysical properties of triptycene molecules.
We also compare all the molecules to each other, discussing the effect of different aromatic phenyl groups in the photophysical properties of molecules. Futhermore, we also discuss the effect of concentration to photophysical properties of triptycene molecules.
Finally, we suggested the development of triptycene molecules in future studies, such as dye-sensitized solar cells, which is the popular research in recent years.
