A series of unprecedented crown ether- and thiacrown ether-derivatized benzene dicarboxylic acid (H2bdc) ligands has been synthesized and incorporated into the prototypical isoreticular metal–organic framework (IRMOF) and UiO-66 materials. In the case of UiO-66, only MOFs comprised from a mixed-ligand composition, requiring both unsubstituted bdc and crown ether containing ligands, could be prepared
Condensation of dicaesium 2-thioxo-1,3-dithiole-4,5-diselenolate(DSIT) with bis-alkylating polythioethers in high dilution leads to the thiacrown compounds 4–7. On treatment with triethyl phosphite, compounds 5–7 are converted into tetrathiafulvalene derivatives 8–10. The crystal structure of 6, and cyclic voltammograms of the tetrathiafulvalenes 9 and 10, are discussed.
