Abstract
Se─Fe─Cu─polymer 系統
藉由 [SeFe3(CO)9Cu2(MeCN)2]‡ 以不單離的方式與不同類型之 dipyridyl ligands 得到一系列新穎的聚合物 [SeFe3(CO)9Cu2(tmdpy)2]n (1a)、[SeFe3(CO)9Cu2(H2bpe)2.5]n (2a)、[SeFe3(CO)9Cu2(H2bpe)]n (2b)、[SeFe3(CO)9Cu2(dpy)3]n (3a)、[SeFe3(CO)9Cu2(dpy)1.5(MeCN)]n (3b) 與 [{Cu(bpe)(MeCN)2}{SeFe3(CO)9Cu(bpe)}(MeCN)]n (4a) 、[{Cu(bpe)- (MeCN)}{SeFe3(CO)9Cu(bpe)0.5}]n (4b) 及化合物 [{SeFe3(CO)9}2- Cu4(bpe)5(MeCN)2•MeCN] (4c)。利用電子吸收光譜與光學全光譜探討其導電度之性質,並藉由 DFT 理論計算佐證其半導體性質,最後利用熱分析質譜儀探討該系列聚合物的熱穩定性。

Furthermore, the formation, nature, photophysical properties, and conductivity of polymers were discussed and elucidated on the basis of DFT calculations.
