Five novel coordination polymers containing N-[(3-carboxyphenyl)-sulfonyl]glycine (H3L), namely [Co3L2(μ2-bipy)2(H2O)6] n ·2nCH3OH·8nH2O (1), [Mn(HL)(μ2-bipy)(H2O)2] n ·nH2O (2), [Mn(HL)(μ2-bipy)(H2O)] n ·3nH2O (3), [Mn(HL)(bipy)(μ2-bipy)0.5(H2O)] n ·4nH2O (4), [Ca(H2O)4Cu2(μ2-bipy)2L2] n ·4nH2O (5) (bipy = 4,4′-bipyridine), were prepared under control by tuning the reaction conditions such as pH value, reaction temperature, and starting materials. X-ray structural analyses of 1–5 reveal their structural diversity ranging from one-dimensional (1D) (1), two-dimensional (2D) (2), and noninterpenetrating 3-D porous coordination polymers (3, 4) to a 2-fold 3D interpenetrating network (5). Compound 1 presents a 1D chain structure with alternating [CoL(H2O)]2 2− binuclear and [Co(4,4′-bipy)2(H2O)4]2+ mononuclear units along the a-axis. Polymer 2, which was formed at a comparatively lower temperature, has a 2D structure extended by a HL2− ligand and a monopillar of bipy. A higher temperature was used in the preparation of 3 and 4. In addition, 3 was synthesized also at a higher pH value. In 3, HL2− ligands link the metal ions to form 2D wavelike rectangle-grid layers which are held together through μ2-bipy molecules in a double-pillar supporting fashion to give a 3D porous framework. A decrease of the pH value led to the formation of another 3D porous framework 4, in which each Mn center binds two trans-located bipy molecules. One bipy behaves as a terminal ligand, while the other one acts as a bridging ligand extending the 2D layers into a unique 3D porous framework. When calcium hydroxide was used, it led to the construction of a 2-fold 3D interpenetrating network of 5 where the Cu atoms are joined by bipy ligands to generate a 1D zigzag chain. The thermogravimetric (TG) and powder X-ray diffraction (PXRD) measurements reveal that both 3 and 4 are stable after dehydration. All of these suggest that the ligand of H3L is a versatile building block for the construction of metal organic frameworks (MOFs).

Herein, a soluble graphene-based material exhibiting the aggregation-induced emission (AIE) feature was prepared for the first time via wet chemistry by the chemical reduction of graphene oxide (GO).

The neutral Cp*M(Cl)(1-PPh(2)-2-S-1,2-C(2)B(10)H(10)) and zwitterionic Cp*M(3-OCH(3)-7-PPh(2)-8-S-7,8-C(2)B(9)H(9)) (Cp* = eta(5)-C(5)Me(5), M = Ir, Rh, 1-PPh(2)-2-S-1,2-C(2)B(10)H(10) = [1-(diphenylphosphino)-2-thiolato)-1,2-dicarba-closo-carborane], 3-OCH(3)-7-PPh(2)-8-S-7,8-C(2)B(9)H(9) = [3-(methoxyl)-7-(diphenylphosphino)-8-(thiolato)-7,8-dicarba-nido-carborane](-)) were synthesized and fully characterized. The 18-electron neutral closo-carborane complexes Cp*M(Cl)(1-PPh(2)-2-S-1,2-C(2)B(10)H(10)) (M = Ir (), Rh ()) can be easily deboronated to result in the formation of reactive 16-electron zwitterionic nido-carborane complexes [Cp*M(3-OCH(3)-7-PPh(2)-8-S-7,8-C(2)B(9)H(9))] (M = Ir (), Rh()). The oxidation of with O(2) gas afforded the corresponding sulfone complex in high yields. Utilization of its unsaturated feature in 16-electron zwitterionic nido-carborane complexes offers a potential strategy to synthesize new types of organometallic complexes.
