The authors of this article (DOI: 10.1080/15685551.2012.705504), which was published online in Designed Monomers and Polymers, wish to make the following change.
The penultimate sentence in section 2.1. Materials [“The solvents such as dichloromethane (CH2Cl2, AR) and tetrahydrofuran (THF, AR) were distilled twice in the presence of CaH2 and potassium, respectively.”] should be replaced by the following two sentences:
“Dichloromethane (CH2Cl2, AR) was distilled twice in the presence of CaH2. Tetrahydrofuran (THF, AR) was distilled twice in the presence of potassium.”
Please note that the sentence has been changed accordingly.
