Description
Summary:碩士 === 國立交通大學 === 應用化學系碩博士班 === 107 === Focusing on this research, our laboratory aimed to synthesize as well as discussing about the molecular structures of fluorophore with different numbers of tetraphenylethene (TPE) attaching on the BODIPY. We hope to metamorphose the phenomenon that BODIPY has (knowing as aggregation-caused quenching effect) into aggregation-induced emission enhancement effect when it presents in solid state. Additionally, we also synthesized a series of BODIPY materials attaching TPE in different positions as well as discussing the changes of fluorescence. In addition, the energy level of HOMO and LUMO were estimating by AC-2 and UVonset, respectively. Finally, utilizing the density functional theory and time-dependent density functional theory to imitate the orbital and energy levels of HOMO and LUMO.
