Essay

The dissertation work is devoted to the development and research of polymeric luminescent sensors based on natural compounds - flavanoids. These sensors can be used for environmental monitoring of environmental pollution by metal ions. The aim of this dissertation is the design and synthesis of polymeric luminescent sensors based on glycidyl derivatives of 3,3‘,4’,5,7 pentahydroxyflavone (quercetin) for the detection of various metal ions, study of their physicochemical, thermal and spectral properties for the further development of luminescent sensors based on them. The object of the research is the synthesis of network polymers based on glycidyl derivatives of 3,3‘,4’,5,7-pentahydroxyflavone and the study of their complexation with ions of various metals. The subject of the study is network polymers based on glycidyl derivatives of quercetin. Study of their structure, physicochemical, thermal, spectral and operational properties. According to the results of the study, the following scientific results were obtained: 1. for the first time synthesised network polymers based on poly(glycidyl ethers of 3,3‘,4’,5,7-pentahydroxyflavone); 2. for the first time the structure of the synthesised mesh polymers was determined and their physicochemical, thermal and spectral properties were investigated; 3. for the first time, transparent films based on network flavonoid-containing polymers were obtained by centrifugation from solutions; 4. for the first time, the influence of the binary solvent acetone-DMSO on the morphology and peculiarities of the formation of the supramolecular structure of polymers and porosity of the obtained polymer films based on networked flavonoid-containing polymers was investigated; 5. for the first time, quantum chemical modelling of the interaction of the obtained network polymers with various metal ions based on the complexation reaction between the corresponding polymer and metal salts was performed; 6. for the first time, was investigated changes in the spectral characteristics of networked quercetin-containing polymers during the formation of chelate complexes with ions of various metals by spectral analysis and the operational properties of the obtained polymeric luminescent sensors was performed. The practical significance of the obtained results is as follows: it was obtained new polymeric materials: thin films based on di-, tri- and tetraglycidyl ethers of quercetin. Due to their structure, complexation processes with metal ions are possible, which makes these compounds promising for use as luminescent sensors for detecting metal ions to monitor environmental pollution by these ions.
