Abstract

Belonging to the field of fluorescent sensors, the invention discloses a fluorescent material for five-membered heterocyclic compound specific detection and a preparation method. The fluorescent material is formed by organic carboxyl ligand and metal coordination, and is called TABD-MOFs for short, and the molecular formula is M(C30H22O4)x(C3H7NO)y. The fluorescent material is obtained by: mixing a DMF solution of metal nitrate, a DMF solution of TABD-COOH, water and ethanol evenly, carrying out reaction at 85DEG C for a period of time, and then conducting filtering and washing. The fluorescent material quickly responds to five-membered heterocyclic high-energy density compounds and has high sensitivity and high selectivity, the detection method is simple and easy to operate, thus being able to completely breaking away from dependence on high precision instruments according to actual needs.

Description

technical field [0001] The invention relates to a fluorescent material and a preparation method for the specific detection of five-membered heterocyclic compounds, in particular to a fluorescent material for the specific detection of five-membered heterocyclic high-energy density compounds based on the principle of aggregation-induced luminescence, which belongs to the technology technology field. Background technique [0002] Among many important high-energy-density materials, five-membered heterocyclic high-energy-density compounds are widely used in the chemical industry. These five-membered heterocyclic high-energy-density compounds with high nitrogen content have significant advantages over conventional high-energy compounds, such as high detonation temperature, high density, good oxygen balance, and low sensitivity to friction and impact. Therefore the detection of these high energy density compounds appears very important (Singh, R.P., Verma, R.D., Meshri, D.T.&Shree...
