Abstract ：
Glycosyl aryl sulfones exhibit diverse biological activities. Herein, we developed a copper-promoted coupling strategy using glycosyl sodium sulfinates and aryl iodides or bromides, enabling efficient synthesis of carbohydrate-based sulfone with broad functional group compatibility. This method offers a versatile approach for the late-stage modification of bioactive molecules.

Abstract ：
Metal-ligand axial coordination of zinc(II) phthalocyanines is an efficient strategy for regulation of structures and properties. In this work, we designed and prepared four unsubstituted zinc(II) phthalocyanine (ZnPc) dimer-based supramolecular complexes (1-4) via axtial coordination with bipyridine derivatives. Single crystal X-ray analysis revealed that the four novel complexes were dimeric (i.e. ZnPc-ligand-ZnPc), with H-shape for 1, saddle-like for 2, and Z-shapes for 3 and 4. It's interesting that a pair of saddle-like dimers of 2 crossed each other to form an interlocked tetramer structure. Furthermore, 3 and 4 were dense stacking because of their semirigid ligands, which significantly enhanced the intermolecular interactions. Intriguingly, in the crystal structure of 4, the naphthalimide ring of the ligand embedded into two neighboring phthalocyanine macrocycles, resulting in a slipped sandwich structure of ZnPc-naphthalimide-ZnPc with double pi center dot center dot center dot pi interactions. More importantly, the strong intermolecular interactions led to very broad absorption spectra in vis-NIR region, quenched fluorescence, and highly efficient photothermal effect. Upon irradiation, 3 and 4 could reach up to 85.7 degrees C and 89.2 degrees C, respectively, enabling them to serve as outstanding photothermal conversion materials used for photothermal imaging and therapy.

Abstract ：
Chiral compounds are known to be important not only because they are the fundamental components of living organisms, but also for their unique chiroptical properties. In recent years, scientists have fabricated several chiral organic supramolecular aggregates by using chiral physical fields, such as vortex flow. Herein, the relationship between dynamic chiroptical properties and rheological nature is discussed, suggesting the shear thinning properties of non-Newtonian fluids might help colloidal particles adopt a chiral arrangement in vortices. Furthermore, the storage modulus of colloids could be increased by adding a linking agent, which successfully kept the dynamic chiroptical properties in the static state. Moreover, the salt effect on the host-guest interaction involved in the colloids was studied, the results suggested a significant enhancement of the transferred dynamic circular dichroism for the achiral guest molecule.

Abstract ：
Two europium(III) coordination polymers (CPs), namely, poly[[diaquabis(mu(4)-1H-benzimidazole-5,6-dicarboxylato-kappa N-6(3):O-5,O-5 ':O-5,O-6:O-6 ')(mu(2)-oxalato-kappa O-4(1),O-2:O-1 ',O-2 ')dieuropium(III)] dihydrate], {[Eu-2(C9H4N2O4)(2)(C2O4)(H2O)(2)]center dot 2H(2)O}(n) (1), and poly[(mu(3)-1H-benzimidazol-3-ium-5,6-dicarboxylato-kappa O-5(5):O-5',O-6:O-6,O-6')(mu(3)-sulfato-kappa O-3:O ':O '')europium(III)], [Eu(C9H5N2O4)(SO4)](n) (2), have been synthesized via the hydrothermal method and structurally characterized. CP 1 shows a three-dimensional network, in which the oxalate ligand acts as a pillar, while CP 2 has a two-dimensional network based on a europium(III)-sulfate skeleton, further extended into a three-dimensional framework by hydrogen-bonding interactions. The structural diversity in the two compounds can be attributed to the different acidification abilities and geometries of the anionic ligands. The luminescence properties of 1 display the characteristic europium red emission with CIE chromaticity coordinates (2/3, 0.34). Interestingly, CP 2 shows the characteristic red emission with CIE chromaticity coordinates (0.60, 0.34) when excited at 280 nm and a near-white emission with CIE chromaticity coordinates (0.38, 0.29) when excited at 340 nm.

Abstract ：
The title compound cytosinium isophthalate (C-H(2)IA) self-assembly of cytosine (C) and isophthalic acid (H(2)IA) in aqueous media has been synthesized and the crystal structure with a reasonable protonation state is redetermined. Single-crystal X-ray diffraction analysis reveals that each asymmetric unit contains one protoned cytosine molecule and one deprotoned isophthalic acid. The proton transferred from carboxylic acid to the pyrimidine ring is disordered across an inversion center with occupancy of 0.5 and the proton located to one of the carboxylate group lies on an inversion center shared by two crystallographically equivalent oxygen atoms. In addition, the cytosine molecules are connected by complementary hydrogen bonds to form a one-dimensional tape structure. The neighboring isophthalic acids are connected via hydrogen bonds between carboxyl groups to form a one-dimensional lattice like tape. Furthermore, the adjacent organic base tapes and organic acid tapes are stacked one with another through pi-pi stacking interactions to form a three-dimensional supramolecular structure. Interestingly, C-H(2)IA displays a green phosphorescence in solid state at room temperature with the lifetime of 0.7 s determined by time resolved studies, indicating that supramolecular C-H(2)IA is a potential pure organic phosphorescent luminogens.

Abstract ：
A novel stilbene-based salicylhydrazone compound {systematic name: (E)-4,4'-(ethene-1,2-diyl)bis[(N'E)-N'-(2-hydroxybenzylidene)benzohydrazide] dimethyl sulfoxide disolvate, C30H24N4O4 center dot 2C(2)H(6)OS or L center dot 2DMSO} was synthesized and characterized by single-crystal X-ray diffraction, powder X-ray diffraction and luminescence spectroscopy. The title compound crystallizes in the monoclinic space group P2(1)/c, with half a symmetry-independent L molecule and one dimethyl sulfoxide (DMSO) solvent molecule in the asymmetric unit. The L molecule adopts an almost planar structure, with a small dihedral angle between the planes of the stilbene and salicylhydrazone groups. There are multiple pi-pi stacking interactions between adjacent L molecules. The DMSO solvent molecules act as proton donors and acceptors, forming hydrogen bonds of various strengths with the L molecules. In addition, the geometry optimization of a single molecule of L and its luminescence properties either in solution, as a solvated solid or as a desolvated solid were studied. The compound shows an aggregation-induced emission (AIE) effect and exhibits switchable luminescence colouration in the solid state by the simple removal or re-addition of the DMSO solvent.

Abstract ：
A rare porous zinc-organic framework with ultrahigh thermal stability over 500 degrees C was obtained, which exhibits a CaF2-type topology formed by 8-connected tetranuclear Zn-4 clusters and 4-connected phosphonocarboxylate ligands. Interestingly, the similar reactions to the zinc-organic framework but in the absence of H2O or by the replacement of Zn2+ with Co2+ can yield three different 3D cluster-based frameworks but with the same CaF2-type topology.

Abstract ：
A series of red light-emitting phosphors Li2Y4-x(MoO4)(7):xEu(3+) were synthesized by a sol-gel method. These samples were characterized by DSC-TGA, XRD, PL and FE-SEM analysis. The best dosage of citric acid is four times of metal ions. The optimal sintering temperature is 900 degrees C. The luminescence intensity of Li2Y4-x(MoO4)(7):xEu(3+) are strongest when the doping concentration of Eu3+ is 4 mol. These phosphors can be excitated by near-UV light of 395 nm and blue light of 465 nm effectively, and show strong red light at 615 nm, which is corresponding to D-5(0) -> F-7(2) transition of Eu3+ ion. The CIE chromaticity coordinates of Li2Eu4(MoO4)(7) phosphor is calculated to be (0.6497, 0.3499), and its lifetime is 0.38 ms. The results show that the phosphor is a promising red component candidate for near-UV and bule LED application. (C) 2016 Elsevier Ltd. All rights reserved.
