Impact of a treatment by plasma polymerization on the filtration performances of commercial membranes for the decontamination of solution containing metal ions.
In this project, a commercial membrane exhibiting low performances of heavy metal removal has been modified by plasma grafting of poly(allylamine). This treatment allows modifying the structural and physicochemical properties of the membrane surface and thus increasing separation performances, while ...
Control of Structures and Emission Properties of (CuI)n 2-Methyldithiane Coordination Polymers
A structurally unique and strongly luminescent nonporous 3D coordination polymer (CP) [Cu8I8(methyldithiane)4]n, CP3, has been prepared in a quasi-anticipated manner from 2-methyl-1,3-dithiane, L1, and CuI. This CP incorporates an unprecedented Cu8I8 cluster built upon two side-fused open cubanes. ...
A Fused Poly(truncated rhombic dodecahedron)-Containing 3D Coordination Polymer: A Multifunctional Material with Exceptional Properties
The design of new and inexpensive metal-containing functional materials is of great interest. Herein is reported a unique thermochromic near-IR emitting coordination polymer, 3D-[Cu8I8(L1)2]n, CP2, which is formed when ArS(CH2)4SAr (L1, Ar = 4-C6H4OMe) reacts with 2 equiv of CuI in EtCN. In MeCN, ...

Physiological parameters of the insect immune system (heamocyte, PO, pro PO) Behavioral parameters of larval defense against natural ennemies (activity, flapping) Parameters of insect reproduction (mating success, fecundity, fertility)
Crystal structure of the coordination polymer catena-poly[[[(acetonitrile-κN)copper(I)]-μ3-1,3-dithiolane -κ3S:S:S'] hexafluoridophosphate]
The polymeric title compound, [Cu2(C2H3N)2(C3H6S2)2](PF6)2, represents an example of a one-dimensional coordination polymer resulting from the reaction of [Cu(MeCN)4][PF6] with 1,3-dithiolane. The cationic one-dimensional ribbon consists of two copper(I) centers each ligated by one acetonitrile ...
Unusual Triplet-Triplet Annihilation in a 3D Copper Chloride Coordination Polymer
A new coordination polymer (CP) defined as [Cu2Cl2(EtS(CH2)4SEt)4]n (CP2) was prepared by reacting EtS(CH2)4SEt with CuCl in acetonitrile in a 1 : 2 stoichiometric ratio. The X-ray structure reveals formation of non-porous 3D material composed of parallel 2D-[Cu2Cl2S2]n layers of Cl-bridged ...
Pure liquid phase recovery in karstic medium
This project is about the study in 2D-cells of fractured media, contaminated by pure phase hydrocarbons. Cosidered systems are made of 3 non-miscible fluids (air, water and hydrocarbons), considering light and dense hydrocarbons. First, the fluids behavior and the distribution of contaminants were ...
Bis{(4-methylthio)phenylthio}methane as assembling ligand for the construction of Cu(I) and Hg(II) coordination polymers. Crystal structures and topological (AIM) analysis of the bonding
The novel 1D coordination polymer (CP) [{Cu(μ2-Br)2Cu}(μ-L2)2] CP2 has been obtained by reaction of the tetrakisthioether p-MeSC6H4SCH2SC6H4SMe-p (L2) with CuBr in a 1:2 metal-to ligand ratio. In contrast to the previously described CP [{Cu(μ2-Br)2Cu}(μ-L1)2] CP1 obtained by reaction of the ...
