[摘要]合成了聚集诱导发光分子四(4,4′,4″,4′″-烯丙氧基)四苯基乙烯(ALTPE ),再利用分散聚合法将ALTPE 与苯乙烯、乙烯基苯磺酸钠交联共聚制备出荧光聚合物微球。利用荧光光谱测试对荧光聚合物微球的性能进行了研究。实验结果表明,

荧光聚合物微球呈单分散球状,粒径尺寸较均匀,紫外光辐照下发出蓝色荧光。荧光聚合物微球悬浮液保持了四苯基乙烯衍

生物的光学特性,且随微球浓度的增大,悬浮液荧光强度不断增强,表现出聚集诱导发光特性。荧光聚合物微球可很好地悬

浮于压裂液中,具有较好的热稳定性;作示踪剂时不需考虑外界pH 变化的影响,同时可以忽略大多数金属离子的可能干扰,

有望应用于油田井间荧光示踪。

[Abstract ]Fluorescent polymer microspheres are prepared by synthesis of tetrakis(4,4′,4″,4′″- allyloxy) tetraphenylethylene(ALTPE),the aggregation-induced emission molecules ,and by

cross-linked polymerization among ALTPE ,styrene and vinyl sodium benzene sulfonate based on

dispersion polymerization. The ?uorescence spectroscopy is used to study the properties of ?uorescent

polymer microspheres. The experimental results show that the ?uorescent polymer microspheres are

monodisperse spherical with a uniform particle size and emit blue fluorescence under UV irradiation.

Fluorescent polymer microspheres suspension retain the optical properties of tetraphenylethylene derivatives.

With the increase of the concentration of the microspheres ,the fluorescence intensity of the suspension

is increasingly enhanced to show the aggregation-induced luminescence properties. Fluorescent polymer

microspheres can suspend well in fracturing fluid with good thermal stability ;when used as tracers ,

?uorescent polymer microspheres are expected to be applied to ?uorescence tracing among oil?eld wells

without consideration of pH value changes and possible interference of most metal ions.

油田注水示踪技术是一种重要的现场测试技

术,广泛应用于油田生产动态监测及评价、改进采

收措施等方面[1-2]。油田开发过程中最常用的示踪

剂主要有化学类[3-5]、放射性同位素[6]和稳定同位素[7]三类,但它们都存在使用量大、成本高、检测灵敏度不好以及严重污染环境等缺点[8]。
