图7 (a) 6种光敏剂与(b) 9种含氟芳香化合物的结构图及其(c)在光照条件下的动态核极化现象热力图. * 颜色值在白色附近时，放大倍率数值在0.8~1.2之间波动，没有明显的超敏化现象. 颜色值越靠近5（红色），信号强度的放大倍率越大，超敏化现象越显著.

Fig. 7 Thermal map of the dynamic nuclear polarization (DNP) phenomenon (c) of 6 photosensitizers (a) and 9 fluorinated aromatic compounds (b) under light conditions. * When the color is white, the magnification value fluctuates around 0.8~1.2, with no significant oversensitization. The closer the color value is to 5 (red), the greater the magnification of the signal strength and the more pronounced the supersensitization phenomenon.
