Postsynthetic modification can be used to introduce sulfonamide functionalities into MOF frameworks. Using sulfonyl chlorides as reactive intermediates, Cr-MIL-SO3H and CAU-1-NH2 have been further modified to give hitherto unknown functionalized MOFs in which a sulfonamide group is bound to the framework either by its N or its S atom.

During recent years monoglyceryl para-aminobenzoate has been used as a chemical "filter" in sunburn preventives, including a few widely sold proprietary preparations. Monoglyceryl para-aminobenzoate has the advantages of a high capacity for filtering out the erythemaproducing portion of the sunlight spectrum, lack of odor, lack of staining properties and high stability under protracted exposure...

In this study, the adsorption mechanism and hydroxyl radical ((•)OH)-initiated photocatalytic degradation mechanism of styrene onto different (TiO2)n clusters were investigated using density functional theory. Styrene, a typical model atmospheric volatile organic compound (VOC), was found to be readily adsorbed onto (TiO2)n clusters through its vinyl group with strong chemisorption. This sugges...

The asymmetric unit of the title co-crystal, C12H14N4O2S·0.5C6H12N2, comprises the sulfonamide mol-ecule and half a mol-ecule of 1,4-di-aza-bicyclo-[2.2.2]octane (DABCO), the latter being disposed about a crystallographic twofold rotation axis. In the sulfonamide mol-ecule, the aromatic rings are almost perpendicular to one another [dihedral angle = 75.01 (8)°]. In the crystal, mol-ecules are c...

The title mol-ecule, C(11)H(15)N(3)O(2)S, features a five-membered ring which is twisted about the middle CH(2)-CH(2) bond. The benzene ring is inclined with respect to the imine residue [C-N-N-C torsion angle = 165.4 (2)°]. Supra-molecular layers in the bc plane are formed by hydrogen bonds between the amine H atoms and sulfonamide O and imine N atoms, as well as by a weak hydrazine H-atom int...

The transformation of indole to indigo by microorganisms expressing styrene monooxygenase (SMO) has been studied. Styrene and indole are structurally very similar, and thus we looked at a variety of styrene-degrading strains for indole transformation to indigo. Two strains, Pseudomonas putida S12 and CA-3, gave a blue color on solid media when grown in the presence of indole. Indole induces its...

An atomic-level strategy is devised to gain insight into the origin of nanogold catalysis by using atomically monodisperse Au(n)(SR)(m) nanoclusters as well-defined catalysts for styrene oxidation. The Au(n)(SR)(m) nanoclusters are emerging as a new class of gold nanocatalyst to overcome the polydispersity of conventional nanoparticle catalysts. The unique atom-packing structure and electronic ...

The molecule of the title compound, C(24)H(36)N(2)O(2)S, displays a U-shaped conformation. The prominent inter-molecular inter-actions are N-H⋯O hydrogen bonds, resulting in the formation of dimers. Additional C-H⋯π contacts involving one of the methyl-ene groups of the macrocycle and the naphthalene rings of a neighbouring mol-ecule stabilize the packing structure. In the crystal structure, th...
