Tiivistelmä
This article describes a detail study about synthesis routes and structures of 3,6-diiodo-9-phenylcabazole(1) and 3,6-diiodo-9-(4’-bromophenyl)carbazole(2). A significance of this study lies in anal zing both the structures and optical, electrical properties through measuring their melting point (M.P.), 1HNMR, infrared spectroscopy (IR), thermogravimetric analysis (TGA) and fluorescence. However, compared with another simple substituted derivatives, the heavy atoms (Br and I) substituted carbazole derivatives obtained much more excellent properties. The compounds possessed high thermal stability and their thermal decomposition temperatures were 273oC and 308oC respectively. 本文具体描述了关于3,6-二碘-N-苯基咔唑和3,6-二碘-N-(4-溴)-苯基咔唑合成路线以及各自分子结构。测量了两个化合物的熔点,核磁氢谱,红外光谱,紫外光谱,热重和荧光性质,重点研究了两个化合物的分子结构,光学性质和电学性质。然而,和其他简单的取代咔唑衍生物比较,溴和碘这类重原子取代的咔唑衍生物拥有更好的热学性质。它们分别在273℃和308℃时开始分解。
