| 摘 要： | 本文利用2-氨基苯并咪唑和5-溴水杨醛反应制得一种具有聚集荧光增强性质的探针L。探针L可以在DMSO体系下对镁离子具有很好的识别效果,并且探针L随着水含量的升高荧光强度在逐渐增强,在水含量达到90%表现出明显的荧光增强现象且发射波长发生明显的红移,在495nm处出现最强发射峰,检测限达到3.49×10-5 M,能够有效地检测Mg2+,同时探针L的AIE性质具有了成为发光材料的潜能。

| Abstract: | In this paper,the reaction of 2-aminobenzimidazole and 5-bromosalicylic aldehyde was used to prepare a probe L with an aggregation-induced emission property.Probe L could had a good recognition effect on magnesium ions under the DMSO system and with the increasing of water content,the fluorescence intensity of the probe L gradually increased.When the water content reached 90%,the probe L showed obviously fluorescence enhancement and the emission wavelength had a significant red shift.The probe L had the strongest emission peak appeared at 495nm,and the detection limit reached 3.49×10-5 M.The probe L could detect Mg2+effectively.At the same time,the probe L had the properties of AIE and had the potential to become a luminescent material. |
