摘要
PROBLEM TO BE SOLVED: To provide an polarization source capable of stably transferring the spin polarization of an electron to the nucleus even in an environment having high oxygen tolerance and the presence of oxygen. SOLUTION: A polarization source of dynamic nuclear polarization composed of molecules represented by the following general formulas. 1 to 6 of Z1 to Z10 represent N, and the others independently represent CR. R represents a hydrogen atom or a substituent, and n represents an integer of 1 to 4. [Selection diagram] None
