Abstract

The invention discloses a phenylsilole-based conjugated microporous polymer. The invention also discloses a preparation method of the phenylsilole-based conjugated microporous polymer, which comprises the following steps: taking a substance A and cyanuric chloride, and carrying out Friedel-Crafts arylation reaction in the presence of a catalyst to obtain the phenylsilole-based conjugated microporous polymer. The invention also discloses an application of the phenylsilole-based conjugated microporous polymer as a fluorescent sensing material. The phenylsilole-based conjugated microporous polymer synthesized by the invention has good chemical stability and thermal stability, and can selectively perform fluorescence sensing on o-nitrophenol in the presence of other substances. The detection method is simple and convenient to operate, visual in signal, high in sensitivity, good in selectivity and capable of realizing real-time in-situ detection.

Description

technical field [0001] The invention relates to the technical field of fluorescence sensing and detection, in particular to a phenylsilolyl-conjugated microporous polymer and a preparation method and application thereof. Background technique [0002] Ortho-nitrophenol (o-NP), one of the isomers of nitrophenol, has produced significant toxic effects on humans, animals, plants, microorganisms, and anaerobic bacteria, posing a significant risk to health. Its toxicity is believed to be due to the fact that the nitro group is easily reduced by enzymes to nitroanion radicals, nitroso and hydroxylamine derivatives, which are cytotoxic, mutagenic and carcinogenic (J.Mol.Sci .2008, 9, 316–326). O-nitrophenol is a chemical intermediate in the production of pigments, rubber chemicals, wood preservatives, photographic chemicals and fungicides. It is highly toxic and has more serious effects on the growth and metabolic activities of organisms, and even pollutes the explosion site nearb...
