Schiff-base condensation of 3,3′,5,5′-tetraformyl-4,4′-biphenyldiol, which was converted from 4,4′-biphenyldiol by a modified Duff reaction, and N,N-diethylethylenediamine in the presence of Zn(CH3CO2)2 followed by the addition of excess NH4PF6 gave a tetrazinc complex [Zn4(L)(μ-CH3CO2)4](PF6)2 (1), where L2- is a new ligand bearing four Schiff-base and two phenoxo-bridging moieties; structure of 1 was fully characterized by X-ray crystallography.

Paragraph 0014, (2021/01/24)
The invention designs and synthesizes a fluorescence sensor capable of singly and selectively identifying toluene, which comprises the following steps: reacting 4, 4'-biphenol and hexamethylenetetramine as substrates in a trifluoroacetic acid solvent to obtain a 4, 4'-biphenol derivative FA; and by taking hydrazine hydrate and 4, 4'-biphenol derivatives as substrates, reacting in absolute ethyl alcohol to obtain a target fluorescence sensor FB. Methanol, ethanol, DMSO, DMF, acetonitrile, acetone, dichloromethane, tetrahydrofuran, ethyl acetate, toluene and cyclohexane are added into an H2O solution of a fluorescence sensor F, it is found that fluorescence of a fluorescence sensor FB can be turned on only when toluene is added, and therefore single selective recognition of the fluorescencesensor FB on toluene molecules is achieved.
Composition for Detecting Acidic Compound

Paragraph 0049-0051, (2020/11/27)
A composition for detecting an acidic compound and a method using the same are discloses herein. In some embodiments, the method includes contacting a composition comprising a metal-organic hybrid structure formed by coordinate bond between a compound represented by the following Chemical Formula 1 or a salt thereof and a metal ion, with an acidic compound to be detected, wherein the composition is in the form of a metallogel prior to contact with the acidic compound, and detecting the acidic compound based on the transition of the composition from the form of a metallogel to a liquid phase. In some embodiments, detection of the acidic compound can be visually confirmed by phase transformation of the composition from a metallogel to a liquid phase.
