近日,中国科学院化学研究所有机固体院重点实验室研究员宋延林与瑞士苏黎世理工学院教授F.Diederich、中科院物理所 研究员高鸿钧等合作,在利用具有推拉电子基团的分子晶态薄膜进行超高密度信息存储研究方面取得了新的进展。 他们在以往的工作基础上,设计合成了具有强电子给体和电子受体、物理化学性质稳定的有机分子1,1,2-tricyano-2- [(4-dimethyl-aminophenyl)ethynyl]ethene(TDMEE)。采用真空沉积的方法,成功地制备出给体-受体反平行规整排列的晶 Recently, the Institute of Chemistry, Chinese Academy of Sciences Institute of Organic Solid State Key Laboratory researcher Song Yanlin and the Swiss Institute of Zurich Professor F.Diederich, Institute of Physics, Chinese Academy of Sciences researcher Gao Hongjun cooperation in the use of a push and pull electronic molecular crystalline thin film ultra-high density information New progress has been made in storage research. Based on their previous work, they have designed and synthesized 1,1,2-tricyano-2- [(4-dimethyl-aminophenyl) ethynyl] ethene (4- TDMEE). Using vacuum deposition method, successfully prepared donor-acceptor anti-parallel aligned crystal
