摘要/Abstract

摘要： 采用Suzuki偶联反应将合成的芴-苯和咔唑-苯共聚物接枝到经化学改性的纸纤维素上,制备了可用于硝基芳烃检测的传感纸纤维素.荧光猝灭研究显示,由于两种传感纸纤维素具有的大比表面积和孔道结构有利于2,4-二硝基甲苯(DNT)蒸气分子的快速扩散,因此二者比薄膜态具有更高的荧光猝灭效率.荧光猝灭的可逆性研究显示,两种传感纤维素经过四次猝灭-恢复循环后,对DNT气态分子依然具有较高的猝灭效率,表明制备的纸纤维素具有良好的荧光猝灭可逆性和稳定性.

Abstract: Sensing celluloses were prepared from fluorene-benzene and carbazole-benzene copolymer grafted to chemical modification of cellulose paper by Suzuki coupling reaction for the detection of nitro-aromatic explosives. Fluorescence quenching studies have shown that, the two kinds of sensor have higher fluorescence quenching efficiency than the thin film state, due to the modified cellulose have a high specific surface area and porosity structure, which are beneficial for the rapid diffusion of DNT vapor molecules. In addition, the two sensing cellulose have shown good fluorescence quenching efficiency after four quenching-recovery circles, which indicates that the sensing cellulose has a good fluorescence quenching reversibility and stability.

Key words: nitro-aromatics, chains aggregation, grafting, fluorescence quenching
