Three different aniline derivatives, namely m- and p-aminobenzoic acids and m-amino benzenesulfonic acid, were sequestered in between layers of a borate-based coordination polymer, based on lead(II) tetrakis(imidazolyl)borate. The aniline derivatives pre-organized in the interlayer spacing of the coordination polymer, and the reactivity of these pre-organized anionic monomers in the crystalline...

Two new nano-sized lead(II) and mercury(II) coordination polymers, [Pb(2-bpdh)(NO3)2(H2O)]n(1); (2-bpdh = 2,5-bis(2-pyridyl)-3,4-diaza- 2,4-hexadiene)} and [Hg(4-bpdb)(SCN)2]n (2); (4-bpdb= 1,4-bis(4- pyridyl)-3,4-diaza-1,3-butadiene) were synthesized by a sonochemical method. The structure of 1 may be considered coordination polymer of lead(II) and Single crystal X–ray analysis of compound ...

The diuretic sulfonamides furosemid (FLFur) and hydrochlorothiazid (H2Hyt) were used as ligands in zinc complexes. Spectroscopic data indicate that in [(HFur)Zn(H 2 0 )2 ]C1 0 4 and (HFur)2Zn the furosemid ligand is bound to zinc via its carboxylate and amine functions while (Fur)Zn(NH3)2 is a coordination polymer with Zn-carboxylate and Zn-sulfonimide coordination. A structure determination sh...

The polymer-copper(II) complex samples, [Cu(phen)(l-Val) BPEI]Cl·H(2)O, with varying degrees of coordination in the polymer chain, were prepared and characterized by elemental analysis and spectroscopic methods. The binding of these complex samples with both DNA and RNA has been investigated. The experimental results indicate that the polyethyleneimine-copper(II) complex samples bind with DNA a...

Growing evidence supports a critical role of dynamic metal-coordination crosslinking in soft biological material properties such as self-healing and underwater adhesion1. Using bio-inspired metal-coordinating polymers, initial efforts to mimic these properties have shown promise2. Here we demonstrate how bio-inspired aqueous polymer network mechanics can be easily controlled via metal-coordinat...

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...

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...

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...

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. ...

A class of carboxyl and carboxylate ester-substituted dithiafulvene (DTF) derivatives and tetrathiafulvalene vinylogues (TTFVs) has been synthesized and their electronic and electrochemical redox properties were characterized by UV-vis spectroscopic and cyclic voltammetric analyses. The carboxyl-TTFV was applied as a redox-active ligand to complex with Zn(II) ions, forming a stable Zn-TTFV coor...
