WebTherefore, it is important to pay attention to the meta-position in the NMR (Nuclear Magnetic Resonance) of the benzene ring. This is called meta-coupling, and when the meta-position of the benzene ring contains a hydrogen atom, the J-value is usually between 1 and 3 Hz. Compared to the ortho position, the J-value is lower due to the distance ... WebA polymer including a self-immolative polymer segment and a thermally-activated trigger moiety is described. The self-immolative polymer segment includes a head end, a tail end, and a plurality of repeating units. The trigger moiety includes a cycloaddition adduct that is covalently coupled to the head end of the self-immolative polymer segment.
