Three novel fluorinated Ln (III) metal-organic frameworks (Ln-F-MOFs) containing holmium for UPJS-21 (Ho), dysprosium for UPJS-21 (Dy), and ytterbium for UPJS-22 (Yb) were prepared and studied. The formulas of compounds were: Ho 2 (L) 3 (DMF) 0. 65 (DMA) 1. 35 ∙0. 75DMF∙0. 75DMA n, Dy 2 (L) 3 (DMF) 0. 65 (DMA) 1. 35 ∙0. 75DMF∙0. 75DMA n, Yb 2 (L) 2 (CH 3 COO) 2 ∙1DMF∙1DMA n. . . .
Princík et al. (Thu,) studied this question.
