Solvent effect on the construction of two microporous yttrium–organic frameworks with high thermostability viain situ ligand hydrolysis

Author affiliations

Abstract

Two novel yttrium trimesates with open frameworks have been synthesized by the self-assembly of trimethyl 1,3,5-benzenetricarboxylate and Y3+ ion in mixed solvent of dimethylformamide (DMF)/water and diethylformamide (DEF)/water, where changes of solvents with different molecular sizes lead to the formation of two similar three-dimensional frameworks with different spatial arrangement styles of the linkers around the Y3+ centers, and solvent-dependent one-dimensional channels (ca. 6.2 × 7.7 Å2) along the [100] direction, as shown by X-ray crystallography. Structural analyses indicate that they have excellent thermal stabilities which are endurable up to 490 °C.
