The interaction of a hydrophobically modified anionic polymer (PMAOVE) with a cationic surfactant (DTAB) was studied using a multi-technique approach: turbidity, surface tension, and viscosity measurements, as well as EPR (5-doxyl stearic acid) and fluorescence (pyrene) probe techniques were used. In the investigated pH range (4-10), the cationic surfactant headgroups interact with the anionic ...

In the title compound, {[Tb(NO(3))(2)(C(6)H(18)N(3)OP)(4)][AgWS(4)]}(n), the polymeric anionic chain {[AgWS(4)](-)}(n) extends along [001]. The Tb(III) atom in the cation is coordinated by eight O atoms from two nitrate and four hexamethylphosphate ligands in a distorted square-anti-prismatic geometry. Together with the two nitrate ligands, the cation is univalent, which leads to the anionic ch...

In the title compound, {[Er(NO3)2(C6H18N3OP)4][AgWS4]} n , the polymeric anionic chain {[AgWS4](-)} n extends along [001]. The Er(III) atom in the cation is coordinated by eight O atoms from two bidentate nitrate anions and four hexa-methyl-phospho-ramide ligands in a distorted square-anti-prismatic geometry. Together with the two nitrate ligands, the cation is monovalent, which leads to the an...

In this paper, we present a tandem anionic-radical approach for synthesizing hypergrafted polymers. We prepared 4-(N,N-diphenylamino)methylstyrene (DPAMS) as a new radical-based inimer. Linear PDPAMS was prepared through anionic polymerization. Hypergrafted PDPAMS was synthesized through the self-condensing vinyl polymerization of DPAMS with linear PDPAMS. The linear backbone of PDPAMS, which i...

The role of lipophilic anionic and cationic additives on the potentiometric anion selectivities of polymer membrane electrodes prepared with various metalloporphyrins as anion selective ionophores is examined. The presence of lipophilic anionic sites (e.g. tetraphenylborate derivatives) is shown to enhance the non-Hofmeister anion selectivities of membranes doped with In(III) and Sn(IV) porphyr...

Different from The liposome-DNA complexes, which were well-known to be used as nonviral vectors for improving the transfection efficiency of gene delivery, we demonstrate a novel type of anionic lipid-DNA (AB-DNA) complexes based on using typical disk-shaped bicelles. Having the advantage of lower cytotoxicity, the approach was proposed to induce anionic DPPG doped bicelles for forming the lame...

The title complex, [Ni(C(12)H(8)N(2))(2)(H(2)O)(2)][Ni(CN)(4)]·C(4)H(8)O·H(2)O, consists of a cationic [Ni(C(12)H(8)N(2))(2)(H(2)O)(2)](2+) unit, an anionic [Ni(CN)(4)](2-) unit, one uncoordinated water and one tetra-hydro-furan mol-ecule. In the cationic unit, the Ni(2+) atom is coordinated by four N atoms and two O atoms from two 1,10-phenanthroline ligands and two water mol-ecules in a disto...

In the title compound, {[Lu(NO(3))(2)(C(6)H(18)N(3)OP)(4)][AgWS(4)]}(n), hexa-methyl-phospho-ramide (hmp), tetra-thio-tungstate, silver iodide and lutetium nitrate were self-assembled, forming an anionic {[AgWS(4)](-)}(n) chain extending parallel to [001]. The Lu(III) atom in the cation is coordinated by eight O atoms from two nitrate groups and four hmp ligands in a distorted square-anti-prism...
