报道了一种新的用于水介质中动态核极化(DNP)实验的双自由基极化剂bTbtk-py。根据最佳理论双自由基体系的要求讨论了合成。迄今为止,由bTbtk-py产生的DNP NMR信号增强是理想甘油/水溶剂基质中任何双自由基中最大的,ε = 230。EPR和X-射线晶体学被用来表征分子,并建议进一步优化的双自由基的距离和相对取向的方法。
A new biradical polarizing agent, bTbtk-py, for dynamic nuclear polarization (DNP) experiments in aqueous media is reported. The synthesis is discussed in light of the requirements of the optimum, theoretical, biradical system. To date, the DNP NMR signal enhancement resulting from bTbtk-py is the largest of any biradical in the ideal glycerol/water solvent matrix, ε = 230. EPR and X-ray crystallography are used to characterize the molecule and suggest approaches for further optimizing the biradical distance and relative orientation.
