中文摘要：

器官的半导体的单个水晶的 nanostructure 在现代 optoelectronic 设备为应用提供材料的一个很有希望的班。然而，形态学控制和高质量的单个水晶的样品的 optoelectronic 性质调整仍然是挑战。这里，我们报导 perylene-3,4,9,10-tetracarboxylic dianhydride (PTCDA ) 的单个水晶的 nanorod 数组的控制形态学的生长。我们证明 PTCDA nanorods 不同于 PTCDA 电影，在可见区域展出光波导特征，提高的吸收，和 Frenkel 刺激排放。另外，我们粗略地测量了 PTCDA nanorods 的电的性质，包括沿着 nanorod 的生长方向的传导性，它是 0.61 S

英文摘要：

The single crystalline nanostructure of organic semiconductors provides a very promising class of materials for applications in modern optoelectronic devices. However, morphology control and optoelectronic property modulation of high quality single crystalline samples remain a challenge. Here, we report the morphology-controlled growth of single crystalline nanorod arrays of perylene- 3,4,9,10-tetracarboxylic dianhydride （IrFCDA）. We demonstrate that, unlike FTCDA film, PTCDA nanorods exhibits optical waveguide features, enhanced absorption, and Frenkel excitation emission in the visible region. Additionally, we measured the electrical properties of PTCDA nanorods, including the conductivity along the growth direction of the nanorod, which is roughly 0.61 S-m i （much higher than that of pure crystalline PTCDA films）.
