TerpyridineCuII-mediated reversible nanocomposites of single-wall carbon nanotubes: towards metallo-nanoscale architectures

Abstract

The self-assembly of Oxi-SWNTs, based on terpyridineCu(II) coordination, produces a thermally stable, neutral [(Oxi-SWNT)(tpyCu(II))m]n nanocomposite possessing notable luminscence properties; quantitative disassembly occurred by treatment with aqueous KCN.

New supramolecular metallo-terpyridine carboxymethyl cellulose derivatives with antimicrobial properties

“…Reaction between CMC and Cu(BF 4 ) 2 -tpyCl created a pentacoordinate complex involving the carboxylate groups of CMC (Wang et al, 2006); two main reactions occur leading to the formation of a complex between at least one carboxylic group of CMC chain and CMC-CltpyCu(BF 4 ) (Scheme 1; product I) or the complex between two carboxylic groups of two different CMC chains and G Model CMC-Cu-Cltpy (Scheme 1; product II). The second reaction needs a specific orientation of two CMC chains and Cu(BF 4 ) 2 -Cltpy and leading to an increase in viscosity and the formation of a crosslinked product possessing low solubility.…”

“…The 4-Cl-terpyridine-Cu(BF 4 ) 2 [Cltpy-Cu(BF 4 ) 2 ] adduct was synthesized according to a previously published procedure (Wang et al, 2006). Reaction of Cltpy-Cu(BF 4 ) 2 (1.5 g, 6.82 mmol) with an aqueous solution of CMC (1 g in 150 mL of water) at 70 • C for 3 h generated the desired CMC-Cu II tpyCl(BF 4 ) (I) along with a minor insoluble, cross-linked CMC-Cu II -tpyCl (II), which was easily filtered.…”

“…Surface modification of OXCNF with Cu-Tpy using an equimolar ratio of Cu-tpy to carboxylic group content of OXCNF is expected to produce a penta co-ordinate complex as shown in scheme 1 [8,19]. Due to water solubility of Cu-Tpy salt, the produced OXCNF-Cu-Tpy possessed hydrophilic character similar to that of OXCNF and a gellike product in water was obtained.…”

Synthesis of Vasorelaxaing 1,4‐Disubstituted 1,2,3‐Triazoles Catalyzed by a 4′‐Phenyl‐2,2′:6′,2′′‐Terpyridine Copper(II) Complex Immobilized on Activated Multiwalled Carbon Nanotubes

“…The sharp absorption bands at 1583.4 cm À1 and 1548.7 cm À1 in spectrum I (Figure 1 a) are attributed to the C=C or C=N bond of PhTPY. [19] Also, the two absorption bands at 1465.8 cm À1 and 1390.6 cm À1 are correlated to the other C=C bonds in the PhTPY ligand. In spectrum II (Figure 1 a), two absorption bands are detected for the C=C or C=N bond at 1610.4 cm À1 and 1575.7 cm À1 , respectively, in the copper complex.…”
