The fabrication of molecular crystal, devices and the physical property measurements for them

在这项研究中，我们的目标是开发一种利用有机分子晶体制造电子器件的技术。这项研究的背景之一是关于分子晶体上FET器件的“超导电性”的报告(Shun等人，自然，406,702(2000))。我们也遵循了他们的程序，并尝试用各种有机晶体作为衬底来制备FET器件。然而，所有的尝试都失败了。随后，我们改变了制备有机薄膜器件的研究计划，并做了以下研究工作：i)以含有[(n-C_7H_&lt；15&gt；)_4N]_2[Fe^&lt；II&gt；(Pc)(CN)_2].的丙酮溶液为原料，制备了一种基于可溶于有机溶剂的酞菁类化合物的光开关器件Ii)“马心细胞色素c发光二极管的研究”我们用生物分子制作了发光二极管，测量了其电致发光(EL)谱。此外，我们还研究了[Fe(Pc)(CN)_2]盐中的巨负磁阻和各种分子导体中的电荷有序现象。

In this study, we aimed to develop a technique to fabricate electronic devices using organic molecular crystals. One of the backgrounds of this study is the report on "superconductivity" for the FET devices fabricated on molecular crystals (Shun et al., Nature, 406, 702 (2000)). We have also followed their procedure and try to fabricate FET devices using various organic crystals as substrates. However all the attempts are failed. Moreover, this report was completely denied later.Then we changed the research plan to fabricate the organic thin-film devices, and have done following research works.i)"The study on a photo-switching device fabricated from phthalocyanines soluble to organic solvents"We fabricated thin films from an acetone solution containing [(n-C_7H_<15>)_4N]_2[Fe^<II>(Pc)(CN)_2]. The fabricated films exhibit the photoswitching phenomenon for UV irradiation.ii)"The study on a light-emitting diode fabricated from horse-heart cytochrome c"We fabricated a light-emitting diode from biomolecule and measured the electro-luminescence (EL) spectra.In addition to these studies, we have studied giant negative magnetoresistance in [Fe(Pc)(CN)_2] salts, and charge-ordering phenomena in various molecular conductors.
