Design and synthesis of new luminescent coordination networks of topology showing the highest degrees of interpenetration

The highest degree of interpenetration reported so far of 7- and 8-fold is realized in two luminescent sql 2D networks by self-assembly of a new nanometric-sized ligand with Ag(i) salts.

Facile Synthesis of 3-(Azol-1-yl)-1-adamantanecarboxylic Acids-New Bifunctional Angle-Shaped Building Blocks for Coordination Polymers

For the first time, orthogonally substituted azole-carboxylate adamantane ligands were synthesized and used for preparation of coordination polymers. The angle-shaped ligands were prepared by the reaction of 1-adamantanecarboxylic acid and azoles (1H-1,2,4-triazole, 3-methyl-1H-1,2,4-triazole, 3,5-dimethyl-1H-1,2,4-triazole, 1H-tetrazole, 5-methyl-1H-tetrazole) in concentrated sulfuric acid. Variation of the solvent and substituents in azole rings allowed to prepare both 1D and 2D copper(II) and nickel(II) coordination polymers, [Cu₂(trzadc)₄(H₂O)_0.7]∙DMF∙0.3H₂O, [Cu(trzadc)₂(MeOH)]∙MeOH, [Ni(trzadc)₂(MeOH)₂] and [Cu₂(mtrzadc)₃(MeOH)]⁺NO₃^– (trzadc-3-(1,2,4-triazol-1-yl)-adamantane-1-carboxylic acid; mtrzadc-3-(3-methyl-1,2,4-triazol-1-yl)-adamantane-1-carboxylic acid) which were structurally characterized by single crystal X-ray diffraction. Complex [Cu(trzadc)₂(MeOH)]∙MeOH was shown to act as a catalyst in the Chan-Evans-Lam arylation reaction.

Non-interpenetrated Cu-based MOF constructed from a rediscovered tetrahedral ligand

A stable non-interpenetrated MOF, UOF-1 (UOF = University of Otago framework), was made by combining the rigid tetrahedral tetrakis(4-carboxyphenyl)adamantane (L) ligand and copper(ii) paddle-wheel SBU. This low-density open framework displayed excellent selectivity for CO₂ over N₂ at practical operating conditions.

Adamantylated organosilatranes: design, synthesis, and potential appraisal in surface modification and anti-protozoal activity

A series of organosilatranes tethered with the privileged adamantane motif has been prepared and their pharmacokinetic profiles were scrutinized.
