Tris(2-(dimethylamino)ethyl)amine (Me6TREN, 97%) was obtained from Sigma-Aldrich (St. Louis, MO, USA). Copper bromide (CuBr, 95.0%) was supplied by Kishida Chemical (Osaka, Japan). Ethanol (99.5%), tetrahydrofuran (THF, 99.5%), and cetylpyridinium chloride (90%) were purchased from Fujifilm Wako Pure Chemical (Osaka, Japan). All chemicals were used as received; 2-Methoxyethyl acrylate (MEA, 98.0%) from Fujifilm Wako Pure Chemical (Osaka, Japan) was treated with an inhibitor-remover prepacked column from Sigma-Aldrich (St. Louis, MO, USA) prior to use. PEO (MW = 500,000 g/mol) was purchased from Fujifilm Wako Pure Chemical (Osaka, Japan). PEO-based macroinitiator (PEO-Br) was prepared and purified in accordance with the literature [28 (link)]. Number average molecular weight (Mn(GPC)) and molecular weight distribution (Mw/Mn) estimated from gel-permeation chromatography (GPC) for PEO-Br were 4.64 × 105 g/mol and 1.23, respectively. The degree of polymerization (DP) for PEO-Br was 11,340. Pyrene (97%) from Fujifilm Wako Pure Chemical (Osaka, Japan) was recrystallized from mEthanol. Water was purified using an ion-exchange column system.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
