Novel compound, preparing method thereof and application of compound in detecting Ti3

The invention relates to the technical field of fluorescence detection, in particular to a novel compound, a preparing method thereof and application of the compound in detecting Ti3+. The structuralformula of the novel compound is shown in the description, wherein R is selected from alkyl groups and ester groups. When the novel compound is used for preparing a fluorescent reagent, the novel compound has a specific response to Ti3+, has no response to Na+, Mg2+, Fe3+, Ba2+, Cd2+, Al3+, Ca2+, Cr3+, K+, Zn2+, Ce3+, Fe2+ and other common metal ions, only has a fluorescence weakening response toTi3+, and can be applied to quickly detecting Ti3+. 本发明涉及荧光检测技术领域，尤其是涉及种新型化合物及其制备方法和在检测Ti中的应用。所述新型化合物，其结构式如下：其中R选自烷基和酯基。本发明的新型化合物用于制备荧光试剂时，对Ti具有特异性响应，对于Na，Mg，Fe，Ba，Cd，Al，Ca，Cr，K，Zn，Ce，Fe等常见的金属离子没有响应，唯独对Ti体现出荧光减弱响应，可应用于Ti的快速检测。
