Аннотация: A novel material based on europium and terbium complexes with a bispidine-substituted benzoate anion for luminescent thermometry in the physiological temperature range was obtained. The obtained complexes demonstrated intense visible luminescence with quantum yields up to 75%, high water solubility, and high luminescence sensitivity toward temperature (S_r = 2.1% K^–1).

Ключевые слова: lanthanide complexes, luminescence, substituted benzoates, luminescent thermometry, biological application, bispidine derivatives.
