Herein, we reported a octahedral Cd3(C3N3S3)2 coordination polymer as a new noble metal-free photocatalyst for robust photocatalytic H2O2 production from methanol/water solution. The coordination polymer can give an unprecedented H2O2 yield of ca. 110.0 mmol • L(-1) • g(-1) at pH = 2.8 under visible light illumination. The characterization results clearly revealed that the photocatalytic H2O2 p...

A coumarin-based Schiff base (receptor 1) exhibited fluorescence enhancement selectively with Zn(2+) at a nanomolar level in near-aqueous medium (EtOH-H2O; 1:1, v/v). The response was instantaneous with a detection limit of 3.26 × 10(-9) M. The sensing event is supposed to incorporate a combinational effect of intramolecular charge transfer (ICT), chelation-enhanced fluorescence (CHEF) and C[do...

For a subtle change in the N-alkyl group of the tridentate ancillary ligand, bis(2-pyridylmethyl)alkylamine (where the alkyl group = methyl (bpma) or ethyl (bpea)), completely different products are formed under similar reaction (in methanol) as well as crystallization conditions (in water). One containing coordinated water molecules is the 3D supramolecular assembly of a tetrameric synthon com...

In the title coordination polymer, [Cu(C(9)H(8)NO(4))(2)](n), the Cu atom, located on a twofold rotation axis, is four coordinate in a distorted square-planar environment. Each 2,6-dimethyl-pyridinium-3,5-dicarboxyl-ate anion bridges two Cu atoms, forming a two-dimensional coordination polymer. A three-dimensional supra-molecular network is built from N-H⋯O hydrogen bonds involving the pyridini...

Hydrothermal reaction of Cd(NO3)2 · 4H2O with a flexible asymmetrical bridging ligand, 4-(2pyrazinylthiomethyl)benzoic acid (Hpztmb), at 120 ◦C yielded a novel one-dimensional Cd(II) coordination polymer [Cd(pztmb)2(H2O)2]n (1), which has been characterized by IR spectroscopy, elemental analysis, thermogravimetry, and X-ray crystallography. The metal-organic chain of the complex is held togethe...

The development of multistimuli-receptive actuators demands a rational combination suitable functionalities. Achieving such actuating properties in single crystalline material is challenge. In spite several investigations on photo-, thermo,- and mechano-responsive crystals, displaying all these effects rare. By judicious photoreactive 2-fluoro-4′-styrylpyridine units flexible Pb3(SCN)3 units, m...

A new nano-sized lead(II) coordination polymer, [Pb(2bpdh)(NO3)2]n(1); (2-bpdh = 2,5-bis(2-pyridyl)-3,4-diaza-2,4hexadiene)}, was synthesized by a sonochemical method. The structure of 1 may be considered coordination polymer of lead(II) consist of metallocyclicchains formed by bridging NO3 and 2-bpdh ligands. The thermal stability of compound was studied by thermal gravimetric and differential...

The thermal stability of C60 dimers and 2D pressure-polymerized C60 is studied using highresolution capacitance dilatometry. The transformation of both the dimer and the polymer phases back to ‘normal’ C60 is excellently described by a simple thermally activated process, with activation energies of 1.75 r 0.1 eV (dimer) and 1.9 r 0.2 eV (polymer). These results are compared to previous data of ...

We provide the in-depth characterization of light-polymer nanowire interactions in the context of an effective Mie scattering regime associated with low refractive index materials. Properties of this regime sharply contrast with these of resonant Mie scattering, and involve the formation of strictly forward-scattered and coupling-free optical fields in the vicinity of core-shell polymer nanowir...

Among the alternative host materials for solid polymer electrolytes (SPEs), polycarbonates have recently shown promising functionality in all-solid-state lithium batteries from ambient to elevated temperatures. While the computational and experimental investigations of ion conduction in conventional polyethers have been extensive, the ion transport in polycarbonates has been much less studied. ...
