To develop printable magneto resistance device, novel organic donor radicals, having characteristic electronic structure, were designed and synthesized. Among them, 5 molecules showed giant negative magneto resistance in their neutral crystalline films. The magneto resistance in these systems are derived from intramolecular interaction between spins in unpaired electrons inπ-organic radical moieties and conduction electrons mediated by the stacking structure ofπ-donor moieties.

为了发展可印刷磁电阻器件，设计合成了具有特征电子结构的新型有机给体自由基。其中5个分子在中性晶膜中表现出巨大的负磁电阻效应。这些体系中的磁阻效应来源于π-有机自由基部分中的未成对电子中的自旋与π-供体部分的堆叠结构介导的传导电子之间的分子内相互作用。
