【摘要】 利用"硅效应"的荧光增强和颜色调节作用^1-2,我们设计合成了两种噻吩官能化硅烷:DPTB-MPS和DPTB-TMS。分别在分散和聚集状态研究了其荧光性质和粒子尺寸。由于分子内旋转受限机理,两种硅烷表现出良好的聚集诱导发光性质,其发光强度和聚集尺寸均随水含量的增加而增强。此外,还研究了其对硝基芳香化合物的荧光猝灭效应。本文为合成新型诱导发光硅烷和硝基化合物荧光探针提供了依据。更多还原

【Abstract】 Taking advantage of fluorescence enhancement and color adjustment of "Silicon Effect",two kinds of thiophene functionalized silanes,DPTB-TMS and DPTB-MPS were designed and synthesized.Their fluorescence properties and particle size were both studied in disperse and aggregate states.Both fluorescence intensity and aggregate size increased as the water content increased.They all exhibited AIEE properties on account of the restriction of intramolecular rotations.Fluorescence quenching behavior to nitroaromatic was investigated.This work may provide guidance for design novel silicon-containing AIEE molecular and fluorescence probe for explosives.更多还原
