LIGAND COMPOUND, AND FUNCTIONALIZED METAL-ORGANIC FRAMEWORK COMPOUND PREPARED BY SAME, PREPARATION METHOD THEREFOR AND APPLICATION THEREOF

摘要

Disclosed are a ligand compound, and a functionalized metal-organic framework compound prepared by same, a preparation method therefor and an application thereof. The structure of the ligand compound is as shown in Formula (I); the ligand compound is used as a ligand to form a functionalized metal-organic framework compound with cadmium chloride by means of self-assembly; the functionalized metal-organic framework compound (LIFM-ZCY-1) has a higher fluorescence quantum yield and a long room-temperature phosphorescence lifetime, and has the advantages of high emission intensity and stable luminous performance; and under vacuum conditions, luminescence is still continued for a long time after an excitation light source is turned off. The LIFM-ZCY-1 does not contain mercury, and is non-toxic, non-volatile, easy to recycle, and environmentally friendly; the composite can be used for anti-counterfeiting by means of room-temperature phosphorescent characteristics and exhibits optical properties negatively correlated with oxygen content, can be prepared into a light-emitting device, an anti-counterfeiting material and/or an oxygen sensor for application, and thus has wide application value.
