Abstract
В работе исследовано влияние "биографических" гостевых молекул на оптические свойства металл-органических каркасных структур с топологией MOF-76 на основе лантаноидов. Был предложен метод термообработки, обеспечивающий наиболее полное удаление гостевых молекул ДМФА из каналов структуры. Показано существование корреляции между величиной сдвига ∆ν = νas(COO-) – νs(COO-) в ИК-спектрах и эффективностью переноса энергии на возбужденные состояния ионов металлов.
The influence of guest molecules on the optical properties of metal organic frameworks with MOF-76 topology based on lanthanides was investigated. A thermal treatment method was proposed that ensures the complete removal of guest DMF molecules from the channels of the structure. The existence of a correlation between the magnitude of the shift ∆v = vas(COO-) – vs(COO-) in the IR spectra and the efficiency of energy transfer to the excited states of metal ions was shown.
