Synthesis and Fluorescent Sensing Application of Porous Organic Polymer Materials

Abstract

Porous organic polymer fluorescence materials have the characteristics of high porosity and outstanding fluorescence properties. The function of fluorescence sensing is given when the skeleton has binding sites with specific analytes, such as nitroaromatic explosives (NAEs), metal ions, anions, gases, organic solvents, etc. In this paper, according to the different types of porous organic polymer materials (POPs), namely the amorphous porous organic polymer materials, crystal porous metal organic framework materials (MOFs) containing coordination bond, and crystal covalent organic framework materials (COFs), the new progress of the POPs fluorescence materials in recent years is reviewed. Especially, the design and synthesis based on functional organic molecules, and their fluorescence sensing applications, are introduced in details. In the future, continuing to design new types of fluorescent COFs from the molecular level is a development direction of highly efficient and recyclable fluorescence chemosensors for detecting NAEs, metal ions, anions, etc.
