Title NUCLEAR SPIN POLARIZATION ENHANCING METHOD THROUGH DYNAMIC NUCLEAR POLARIZATION BY USING SOLUBLE PENTACENE NEW_EN
Abstract An object is to provide a method for enhancing a nuclear spin polarization. Triplet DNP where a pentacene derivative represented by the following formula (A) is used as a polarizing agent enables an effective enhancement in nuclear spin polarization to be achieved. In formula (A), each R independently represents a hydrogen atom (-H), a deuterium atom (-D), or a hydrocarbon group having 1 to 20 carbon atoms which optionally includes at least one atom selected from the group consisting of an oxygen atom, a sulfur atom and a silicon atom, provided that at least one R represents a hydrocarbon group having 1 to 20 carbon atoms which optionally includes at least one atom selected from the group consisting of an oxygen atom, a sulfur atom and a silicon atom.
