Abstract:

Molecules based on the 1,4-bis(phenylethynyl)benzene (BPEB) architecture are an important class of compounds because of their luminescent properties. The rigid rod-like backbone and extended π-conjugation serves as the base upon which a wide variety of substituted species can be synthesised with a variety of photophysical properties. This thesis represents a detailed study of the photophysical properties of a series of compounds based on BPEB using a combination of steady-state and time- resolved spectroscopic methods.

碩士<br>國立臺灣師範大學<br>化學研究所<br>91<br>The photochemical and photophysical properties of moiety “tropolone” in colchicine〈1〉and thiocolchicine〈5〉were studied. Irradiation of colchicine〈1〉in methanol gives mainly two photoproducts：β－lumicolchicine〈2〉andγ－lumicolchicine〈3〉. Further irradiation of β－lumicolchicine〈2〉in methanol gives the photoproduct ofα－lumicolchicine〈4〉. Irradiation of thiocolchicine〈5〉in methanol gives mainly two photoproductsβ－lumithiocolchicine〈6〉andγ－lumithiocolchicine〈7〉. The low lying（π、π*） excited singlet state is responsible for the photochemistry of colchicine〈

碩士<br>國立中山大學<br>化學系研究所<br>95<br>In attempting to modulate the electronic properties of molecular-wire Ru(II) complexes, we now describe an interesting example of X-tpy-Ru2+-tpy-(fc)2-tpy-Ru2+-tpy -X ( fc = ferrocenyl ; tpy = terpyridyl ; X=Cl, OMe, OH ) complexes comprising electronic donor or withdrawing group attached directly to the 4’-position of the terminal tpy moiety. The ground-state HOMO and LUMO energies were probed by electrochemical measurements and the excited-state photophysical properties were probed by absorption spectroscopy.

The results showed that these electrophosphorescent materials exhibited good thermal stability with 5% weight loss temperatures which were above 300℃ in nitrogen atmosphere. The amorphous solid films of electrophosphorescent materials were seen clearly from the polarization microscopy images

The molecular aggregation and the luminescent property in solid and solution were studied in this thesis. First of all, in the solid the compounds of the first and third category associate by a AuI-AuI interaction. The compound of the se
