Cu(I)-based fluorescent metal organic skeleton, and preparation method and application thereof

The invention belongs to the technical field of fluorescent sensing, and particularly discloses a Cu(I)-based fluorescent metal organic skeleton, and a preparation method and application thereof. TheCu(I)-based fluorescent metal organic skeleton is applied to detection of nitrobenzene by fluorescence sensing. The chemical formula of the Cu(I)-based fluorescent metal organic skeleton is {(Cu2I2)2[Cu6(dmpymt)6]}n; the Cu(I)-based fluorescent metal organic skeleton contains two basic units, namely, Cu6S6 and Cu2I2; the metal organic skeleton which is constructed on the basis of the two units isfound for the first time, and has certain innovative significance and research value. The compound is prepared through a solvothermal method, is simple in process, high in purity and high in reproducibility, and has an obvious sensing effect on nitrobenzene; moreover, a specific phenomenon that fluorescence is recovered again after being quenched can be achieved by changing excitation wavelength;the compound has obvious se
