| Summary: | 碩士 === 國立中央大學 === 化學研究所 === 93 === This thesis reports the synthesis of isotruxene, and the synthesis, fluorescence and thermal properties of its derivative ITF.
There is currently only one paper in the literature related to the synthesis of isotruxene, and its yield was low. We happened to synthesize isotruxene with indene and 2-bromopyridine under palladium-catalyzed condition, but its isolated yield is only 9%. Therefore one of our research goal is to promote its yield. In addition, its isomer truxene, which has a symmetrical C3 structure, has attracted much attention in recent years. Therefore, we would like to compare the physical properties of the derivatives of truxene and isotruxene, for example, in terms of their luminescent behavior. We have thus synthesized the isotruxene derivative ITF and compared with the truxene derivatives T1-T4.
The results showed that compound ITF and compound T4 have nearly the same fluorescence emission energies, thermal and electrochemical stabilities, which might prove of value being a blue emitter.
