Synthesis and Optical and Electrochemical Properties of Symmetrically Arranged Carbazole Dendrimers

采用乌尔曼缩合反应合成了新型的咔唑基树状分子;利用核磁共振谱仪(1HNMR,13CNMR)和飞行时间质谱仪(MALDI-TOF-Mass)对其进行了表征;并评价了树状分子的荧光性能和电化学性能.结果表明,所合成的咔唑基树状化合物在394nm处发蓝光,同时具有低的HOMO能级.

One novel carbazole dendritic compound was synthesized by using modified Ullmann condensation reaction. The product was characterized by means of nuclear magnetic resonance （^1H NMR, ^13C NMR） spectroscopy and time-of-flight mass spectrometry （MALDI-TOF- Mass）. At the same time, the luminescent property and electronic property of the product were evaluated. Results show that the synthetic compound exhibits blue fluorescence at a maximum wavelength of 394 nm and low energy level of highest occupied molecular orbital （HOMO） as well.
