Abstract

The invention provides a dye and metal organic framework material having the formula {[In3O L1.5(H2O)3](NO3)0.7(C16H7O10S3)0.1}(C4H9NO)3(CH3CN)6(H2O)25, wherein C4H9NO is N, N' is dimethylacetamide, C16H7O10S3 is 8-hydroxy hydrazine, 1,3,6-trisulphonic acid trisodium salt, CH3CN is acetonitrile, the crystal structure of the dye and metal organic framework material belongs to the cubic system, andthe space group is as shown in the description, the unit cell parameter is as shown in the description, [alpha]=[beta]=[gamma]=90 degrees, and unit cell volume is as shown in the description. The dyeand metal organic framework material has the following beneficial effects: 1. a proper dye molecule with a proton carrier is selected to be introduced into a pore of a metal organic framework to prepare the dye and metal organic framework material as a proton conducting material and a fluorescence detector while increasing the proton conductivity and detecting the sensitivity of small organic molecules.

Description

technical field [0001] The invention relates to a dye@metal organic framework material and its preparation method and application, belonging to the technical field of metal organic framework materials. Background technique [0002] Proton Exchange Membrane Fuel Cell (PEMFC) is a power generation device that directly converts the chemical energy of fuel into electrical energy without combustion. It has a high energy conversion rate and is environmentally friendly and pollution-free. It is considered to be the first choice in the 21st century. efficient and clean power generation technology. Proton exchange membrane (PEM) is one of the key materials of PEMFC, which has the function of conducting protons and isolating fuel and oxidant. At present, the most researched and applied is the perfluorosulfonic acid membrane (PFSA) represented by Nafion, whose proton conductivity can be as high as 10% in the temperature range of 60-80°C and 98% high humidity. -1 ~10 -2 S cm -1 .
