The project has been targeting the synthesis of new crystalline materials with two-dimensional-layered hybrid architectures comprising C60 and polyaromatic hydrocarbon building blocks. This has been successful for the polyaromatic hydrocarbon, triphenylene. The resulting strongly-correlated Mott insulating phases have been structurally characterized down to cryogenic temperatures and reveal unique architectures and a variety of phase transitions. They have now been chemically manipulated to afford crystalline reduced materials with two-dimensional architectures. Their properties focusing on metallicity and superconductivity are being actively pursued.

该项目的目标是合成具有二维层状混合结构的新型晶体材料，其中包括 C60 和聚芳烃结构单元。这对于多芳烃苯并菲来说是成功的。由此产生的强相关莫特绝缘相已在低温下进行了结构表征，并揭示了独特的结构和各种相变。现在，它们经过化学处理，可提供具有二维结构的结晶还原材料。人们正在积极研究它们的金属性和超导性特性。
