Usability and Effectiveness of eHealth and mHealth Interventions That Support Self-Management and Health Care Transition in Adolescents and Young Adults With Chronic Disease: Systematic Review.

Background: With advances in medical technologies, more children with chronic diseases are now living on into adulthood. The development of proficient self-management skills is essential for adolescents and young adults to transition from pediatric to adult health care services. An innovative way to improve the current care model and foster self-management skills could be through eHealth or mHealth (mobile health) interventions, in particular, when considering the rising ownership of digital technology by adolescents and young adults.

Zinc(II)-Based Ring-and-Rod Coordination Layer as an Excitation-Wavelength-dependent Dual-Emissive Chemosensor for Discriminating Fe, Cr, and Al in Water.

The reactions of Zn(NO), 3,6-(pyridin-3-yl)-9-carbazole (bpycz), and 2,5-dihydroxyterephthalic acid (Hdhbdc) or 2-bromoterephthalic acid (Br-1,4-Hbdc) under hydro(solvo)thermal conditions yielded corresponding coordination polymers (CPs) {[Zn(Hdhbdc)(bpycz)]•0.5HO} () and [Zn(Br-1,4-bdc)(bpycz)]•2DMAc•HO (), respectively, with high thermal stability approaching 350 °C. CP adopts a ring-and-rod layer structure, which is topologically described as a 4-connected net with the point symbol of 2•6.

A neutral rhenium-biimidazole complex for the selective recognition of fluoride ions.

The neutral rhenium(I)-biimidazole complex [Re(CO)(biimH)(1,4-NVP)] (1) was designed and synthesized by a one-pot reaction of Re(CO), 2,2'-biimidazole (biimH) and 4-(1-naphthylvinyl)pyridine (1,4-NVP). The structure of 1 was characterized by various spectroscopic techniques including IR, H NMR, FAB-MS, and elemental analysis and further confirmed by a single-crystal X-ray diffraction analysis. The mononuclear complex 1, a relatively simple structure with an octahedral geometry, is comprised of facial-arranged carbonyl groups, one chelated biimH monoanion, and one 1,4-NVP.

XRPD patterns prove that TbP and EuP are isomorphous and isostructural.

Aggregation-induced emission enhancement (AIEE) of tetrarhenium(I) metallacycles and their application as luminescent sensors for nitroaromatics and antibiotics.

The self-assembly of tetrarhenium metallacycles [{Re(CO)}(μ-dhaq)(μ-N-N)] (3a, N-N = 1,3-bis(1-butylbenzimidazol-2-yl)benzene; 3b, N-N = 1,3-bis(1-octylbenzimidazol-2-yl)benzene), (H-dhaq = 1,4-dihydroxy-9,10-anthraquinone) and [{Re(CO)}(μ-thaq)(μ-N-N)] (4, N-N = 1,3-bis(1-butylbenzimidazol-2-yl)benzene), (H-thaq = 1,2,4-trihydroxy-9,10-anthraquinone) under solvothermal conditions is described. The metallacycles 3a,b and 4 underwent aggregation-induced emission enhancement (AIEE) in THF upon the incremental addition of water. TEM images revealed that metallacycle 3a in a 60% aqueous THF solution formed rectangular aggregates with a wide size distribution, while a 90% aqueous THF solution resulted in the formation of a mixture of nanorods and amorphous aggregates due to rapid and abrupt aggregation.

Fluorescence-Responsive Detection of Ag(I), Al(III), and Cr(III) Ions Using Cd(II) Based Pillared-Layer Frameworks.

Two Cd(II) based coordination polymers, {Cd(btc)(BTD-bpy)]∙1.5MeOH∙4HO} () and [Cd(1,4-ndc)(BTD-bpy)] (), where BTD-bpy = bis(pyridin-4-yl)benzothiadiazole, btc = benzene-1,3,5-tricarboxylate, and 1,4-ndc = naphthalene-1,4-dicarboxylate, were hydro(solvo)thermally synthesized.

Hetero-interpenetrating porous coordination polymers.

Interpenetrating porous coordination polymers (IPCPs) consist of two or more networks that are mechanically interlocked to form a coherent structure. The framework topology and the chemical composition are the two important criteria of interpenetrating networks to distinguish homo-IPCPs from hetero-IPCPs. Compared to rich homo-IPCPs, hetero-IPCPs remain rare and are formed rather unexpectedly.

Complexes {[Zn(bpdc)(Cz-3,6-bpy)]·DMF·HO} (-DMF, Hbpdc = biphenyl-4,4'-dicarboxylic acid, Cz-3,6-bpy = 3,6-bis(pyridine-4-yl)-9-carbazole, DMF = ,'-dimethylformamide) and {[Zn(bpdc)(Cz-3,6-bpy)]·2DMAc·HO} (-DMAc, DMAc = ,'-dimethylacetamide) as a couple of solvent-induced supramolecular isomers were hydro(solvo)thermally synthesized using DMF/HO and DMAc-only as reaction media, respectively. Complexes -DMF and -DMAc adopt very similar wavy sheet structures but present great differences in the 3-fold interweaving 2D → 2D nets, which result in free voids of 17.6 and 33.

Paddlewheel SBU based Zn MOFs: Syntheses, Structural Diversity, and CO₂ Adsorption Properties.

Four Zn metal⁻organic frameworks (MOFs), {[Zn₂(2,6-ndc)₂(2-Pn)]·DMF} (), {[Zn₂(cca)₂(2-Pn)]·DMF} (), {[Zn₂(thdc)₂(2-Pn)]·3DMF} (), and {[Zn₂(1,4-ndc)₂(2-Pn)]·1.5DMF} (), were synthesized from zinc nitrate and ,'-bis(pyridin-2-yl)benzene-1,4-diamine (2-Pn) with naphthalene-2,6-dicarboxylic acid (2,6-H₂ndc), 4-carboxycinnamic acid (H₂cca), 2,5-thiophenedicarboxylic acid (H₂thdc), and naphthalene-1,4-dicarboxylic acid (1,4-H₂ndc), respectively.

An Unprecedented Interpenetrating Structure Built from Two Differently Bonded Frameworks: Synthesis, Characteristics, and Efficient Removal of Anionic Dyes from Aqueous Solutions.

The first example of one single crystal (NTOU-5) containing two different organic-inorganic hybrid open-framework structures was obtained using a hydro(solvo)thermal method and structurally characterized by single-crystal X-ray diffraction. Remarkably, under the same synthetic conditions, the zinc ions are respectively coordinated by oxalic acid (OX) and 1,2,4,5-tetrakis(imidazol-1-ylmethyl)benzene (TIMB) linkers to form two significantly different frameworks: anionic [Zn (OX) ] and cationic [Zn(TIMB)] networks that interweave with each other to give an unprecedented interpenetrating structure with two differently-bonded open-frameworks. From the inorganic chemistry perspective, it is extremely difficult to control to which metal center the oxygen-donor linkers or/and nitrogen-donor ligands bind.

Two-fold 2D + 2D → 2D interweaved rhombus (4,4) grid: synthesis, structure, and dye removal properties in darkness and in daylight.

Compound [Cu(NI-mbpy-44)2(NO3)2]·4H2O (1, NI-mbpy-44 = N-(pyridin-4-ylmethyl)-4-(pyridin-4-yl)-1,8-naphthalimide) adopting a two-dimensional (2D) periodical rhombus (4,4) grid has been synthesized. This grid doubly interweaves in a parallel fashion to result in overall 2D + 2D → 2D networks with approximately 14% sufficient free volumes in which lattice H2O molecules reside. Dye removal studies show that 1 selectively adsorbs anionic methyl orange (MO) and acid orange 7 (AO7) over cationic methylene blue (MB) and malachite green (MG) from aqueous solutions containing single or mixed dyes in darkness at room temperature.

Single-crystal X-ray structure analysis reveals that adopts a six-connected two-dimensional (2D) chiral layer structure with 3⁶- topology. Dye adsorption explorations indicate that readily adsorbs methyl blue (MyB) from water without destruction of crystallinity.

Anion-Directed Metallocages: A Study on the Tendency of Anion Templation.

Self-assembly of Cu(NO ) ⋅3 H O and di(3-pyridylmethyl)amine (dpma) with addition of different acids (HNO , HOAc, HCl, HClO , HOTf, HPF , HBF , and H SO ) afforded a family of anion-templated tetragonal metallocages with a cationic prismatic structure of [(G )⊂{Cu (Hdpma) }] (G =NO , PF , SiF ) with different ligating anions/solvents (NO , Cl , ClO , OTf , H O) outside the cage. Systematic competitive experiments have rationalized the tendency of anion templation towards the formation of metallocages [(G )⊂{Cu (Hdpma) }] as occurring in the order SiF ≈PF >NO >SO ≈ClO ≈BF . This sequence is mostly elucidated by shape control over size selectivity and electrostatic attraction between the cationic {Cu (Hdpma) } host and the anionic guests.

Anion-Directed Copper(II) Metallocages, Coordination Chain, and Complex Double Salt: Structures, Magnetic Properties, EPR Spectra, and Density Functional Study.

A series of Cu(II) metallo-assemblies showing anion-directed structural variations, including five metallocages [(G(n-) )⊂{Cu2 (Hdpma)4 }]((8-n)+) (A(-) )8-n (G(n-) =NO3 (-) , ClO4 (-) , SiF6 (2-) , BF4 (-) , SO4 (2-) ; A(-) =NO3 (-) , ClO4 (-) , BF4 (-) , CH3 SO4 (-) ; Hdpma=bis(3-pyridylmethyl)ammonium cation), a complex double salt, namely, (H3 dpma)4 (CuCl4 )5 Cl2 , and a coordination chain, namely, [Cu2 (dpma)(OAc)4 ], are reported. The influence of the anion can be explained by its coordinating ability, the affinity of which for the Cu(II) center interferes significantly with metallocage formation, and its shape, which offers host-guest recognition ability to engage in weak metal-anion coordination and hydrogen bonding to the organic ligand, which are responsible for metallocage templation. EPR studies of these metallocages in the powder phase at room temperature and 77 K showed a trend of the g values (g|| >2.

Reversible Single-Crystal to Single-Crystal Transformations of a Zn(II)-Salicyaldimine Coordination Polymer Accompanying Changes in Coordination Sphere and Network Dimensionality upon Dehydration and Rehydration.

A fluorescent Zn(II)-salicyaldimine coordination polymer, [Zn(L(salpyca))(H2O)]n (1; H2L(salpyca) = 4-hydroxy-3-(((pyridin-2-yl)methylimino)methyl)benzoic acid), showing a one-dimensional (1D) zigzag chain structure has been hydro(solvo)thermally synthesized. Removal of coordination water molecules in 1 by thermal dehydration gives rise to the dehydration product [Zn(L(salpyca))]n (1'), which has a dizinc-based two-dimensional (2D) gridlike (4,4)-layer structure. X-ray powder diffraction (XRPD) patterns, thermogravimetric (TG) analyses, and infrared (IR) spectra all clearly indicate that the structure of 1 is quite flexible as a result of a reversible 1D-2D single-crystal to single-crystal (SCSC) transformation upon removal and rebinding of coordination water molecules, which accompanies changes in coordination sphere and network dimensionality.
