Abstract

The invention discloses a manganese-based luminous metal organic framework material and a preparation method thereof and application thereof. The chemical formula of the manganese-based luminous metalorganic framework material is {[Mn(tipe)(1, 4-ndc)(H2O)].(DMF)2.(H2O)3}n. The preparation method comprises the steps of mixing manganese chloride tetrahydrate, tipe and 1, 4-naphthalic acid accordingto a ratio; adding N, N-dimethyl formamide and water to an obtained mixture; and stirring the mixture; putting the mixture into a high temperature resistant glass bottle; and after enabling the mixture to react for 2-3 days at 85-95 degrees centigrade and slowly cooling a reaction product to room temperature, filtering the cooled reaction product to obtain a yellow rod-like crystal, wherein the yellow rod-like crystal is the manganese-based luminous metal organic framework material. The manganese-based luminous metal organic framework material, disclosed by the invention, has the advantages that the fluorescence quantum yield is very high, and potential application values in the fields such as light emitting diodes, biological imaging and fluorescence detecting are realized. The manganese-based luminous metal organic framework material with an excellent fluorescence characteristic shows rapid and efficient fluorescence detecting performance to Fe<3+>.
