After arthroscopic subchondral drilling, this novel technique may result in better articular cartilage regeneration.

Two 1H-imidazol-4-yl-containing ligands 1,3-di(1H-imidazol-4yl)benzene (L 1 ) and 4,4′-di(1H-imidazol-4-yl)biphenyl (L 2 ) were employed to react with corresponding metal salt together with varied carboxylate ligands under hydro-and solvothermal conditions, and six new metal−organic frameworks 6) [H 2 oba = 4,4′-oxybis-(benzoic acid), H 3 BPT = biphenyl-3,4′,5-tricarboxylic acid, H 4 BPTC = biphenyl-3,3′,5,5′-tetracarboxylic acid, DMF = N,N-dimethylformamide] were achieved and structurally characterized. MOFs 1, 3, 4, and 5 are different two-dimensional networks, which are further joined together by hydrogen bonds to generate three-dimensional (3D) supramolecular frameworks. 2 is a (4,4)-connected binodal 3D framework with a point symbol of {3•4•5•8 3 } 4 {3 2 •8 2 •9 2 }, while 6 is a diamond 3D framework. The results show that coordination geometry of the metal centers and coordination mode of the ligands play important roles in the formation of MOFs with diverse structures. Moreover, luminescent studies showed that 1 and 3 represent highly efficient quenching for detecting Fe 3+ ions and acetone molecules. In addition, 6 exhibits selectively adsorption of CO 2 over N 2 .

Four new metal-organic frameworks (MOFs) [Zn(L)(bpdc)]·1.6HO (1), [Co(L)(bpdc)]·HO (2), [Ni(L)(bptc)(HO)]·2HO (3) and [Cd(L)(Hbptc)] (4) were achieved by reactions of the corresponding metal salt with mixed organic ligands of 1,4-di(1H-imidazol-4-yl)benzene (L) and 4,4'-benzophenonedicarboxylic acid (Hbpdc) or biphenyl-2,4',5-tricarboxylic acid (Hbptc). They exhibit varied structures: MOFs 1 and 4 are porous three-dimensional (3D) frameworks, while 2 is an infinite one-dimensional (1D) chain and 3 is a two-dimensional (2D) network. Remarkably, 1 and 4 can act as potential fluorescent materials for sensing Fe(iii) ions and different ketone molecules with high selectivity and sensitivity. In addition, MOF 1 shows selective adsorption of CO over N.
