Исследование фотофизических и фотохимических свойств цинковых комплексов дипиррометенов

Abstract

Study of complexes of dipyrromethene with different structure is one of the most successfully developing areas of modern chemistry. The demand for using a variety of optical devices in modern technology makes it necessary to explore the photonics of new organic luminophores (coordination complexes of dipyrromethene with p- and d-elements) depending on their structure, intermolecular interactions, temperature, etc. In this work was researched dipyrromethene compounds, which can form stable complexes with ions of delements. The main advantage complexes of Zn(II) with dipyrromethens is easy to "self-assembly" in the "soft" conditions on complexing ions in solutions and in biological systems, as well as high sensitivity spectralluminescence characteristics to changes in the structure of the chromophore and the nature of the solvent. Systematic observation of photochemical and photophysical properties and establishment of their connection with structural features of the complexes are required for successful usage of dipyrromethene complexes and creation of various hi-tech optical devices which are based on them. Therefore, the purpose of the work is to study the spectral-luminescent, sensory properties of different complexes of dipyrromethenes with zinc, the optimal combination of which will indicate the direction of the most effective use of these dyes. In the study of a number of complexes of dipyrromethens found that the introduction of various substituents in the dye structure significantly affects on photonics of luminophores.
