実験手順

First, poly(2-vinylpyridine) homopolymer was prepared by using 2-vinylpyridine (2VP) monomer at −78° C. and under high vacuum (10−6 torr) in the solvent of THF for 30 min. The temperature of −78° C. is maintained by adding dry ice in a constant-temperature bath with acetone, and measured with a thermometer for low temperature. The initiator of potassium diphenylmethane (DPM-K) was prepared by reacting potassium-naphthalene (K-NaPh) ion solution with diphenylmethane, and diluted to appropriate concentration using a distribution device connected to vacuum line. The initiator was divided into glass ampoules and stored in a low temperature refrigerator.
