The synthesis and characterization of a biradical containing a 1,3-bisdiphenylene-2-phenylallyl (BDPA) free radical covalently attached to a 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO) free radical are described. The synthesis of the biradical is a step toward improved polarizing agents for dynamic nuclear polarization (DNP).
本文描述了一种双自由基的合成与表征,该双自由基含有一个与2,2,6,6-四甲基哌啶-1-氧基(TEMPO)自由基共价连接的1,3-双亚苯基-2-苯基烯丙基(BDPA)自由基。该双自由基的合成是朝着改进用于动态核极化(DNP)的极化剂迈出的一步。
