Preparation method of luminous crystal material capable of selectively detecting Fe<3+> ions

The invention discloses a preparation method of a luminous crystal material capable of selectively detecting Fe ions. 4-amidogen-3,5-di(3-pyridyl)-1,2,4-triazole (3-abpt) and zinc nitrate hexahydrate are added into a mixed solution of acetonitrile and N,N'-dimethyl formamide to be stirred to be prepared into a solution; 1,4-naphthalic acid (1,4-ndc) is added into the prepared solution to be stirred until the solution is clear; the solution is put into a sealed reaction kettle for heating reaction for three days; after the temperature is slowly lowered, filtering, washing and drying are performed to obtain the luminous crystal material {[Zn2(1,4ndc)2(3abpt)].H2O}n. The preparation method has the advantage that the luminous crystal material {[Zn2(1,4ndc)2(3abpt)].H2O}n capable of efficiently and selectively detecting the Fe ions is obtained. 本发明公开了种具有选择性探测Fe离子的发光晶体材料的制备方法。将4-氨基-3,5-二(3-吡啶基)-1,2,4-三氮唑(3-abpt)和六水合硝酸锌加入到乙腈与N,N'-二甲基甲酰胺混合溶液中搅拌制得溶液；将1,4-萘二甲酸(1,4-ndc)加入到上述制得的溶液中搅拌至澄清，并将该溶液置于密闭反应釜中加热反应三天，缓慢降温后经
