In a polymerization tube, in which the ATRP method had been used as macroinitiator: CuBr
: 2, 2'-bipyridyne: monomer: have been placed with regard to the rates of 1: 1: 2: 100 (mol) respectively.
Hence, the reduction and formation of Cu NWs is favored at high solubility of intermediate products in the solvent as in the cases of CuCl and CuBr
. But, in the case of low solubility CuI, the products resulted to be a mixture of CuI, [Cu.sub.2]O, and Cu phases (Figure S2).
Ingalls, "Extended x-ray--absorption fine-structure study of anharmonicity in CuBr
," Physical Review B, vol.
[P.sub.VBC-DVB] microspheres (2g) were placed in another 100 mL round-bottom flask and 0.1952 g Bpy and 0.0284 g CuBr
were added to a self-made N2 circulation device.
Three catalysts (CuI, CuBr
, and CuBr[([PPhe.sub.3]).sub.3]) and four ligands (TEA, DBU, DIPEA, and PMDTA) were examined in one-pot/two-step/three-component synthesis of click SGP.
(2.87 g) and PMDETA (3.46 g) were added to 15 mL of anisole in a glove box.
In the case of Antonin Dvorak the first complete edition project, under the Editing Board for the Works of Antonin Dvorak (its members were Otakar Sourek, Frantisek Bartos, Jan Hanus, Jiri Berkovec, Jarmil Burghauser, Antonin Cubr
, Antonin Pokorny and Karel Solc), was officially launched in the year of the fiftieth anniversary of the composer's death (1954), when his works had come "free" in accordance with the then law of copyright.
Termination reactions are prevented in ATRP by the presence of a metal complexing agent, such as CuBr
, which reversibly caps the growing radical chain.
The use of CuBr
in anhydrous THF gave the best results.
Tetrahydrofuran (THF), methanol, ethanol, n-hexane, 1,4-dibromobutane, 2,2'-bipyridine (bpy), N,N-tetraethylthiuram disulfide (TD; Tokyo Kasei Organic Chemicals, Tokyo, Japan), silver nitrate (AgN[O.sub.3]), potassium thiocyanate (KCNS), hydrochloric acid (HCl) and copper(I) bromide (CuBr
; Kanto Chemicals, Tokyo, Japan) were used as received.
