摘要:
酞菁铜(CuPc)因其特殊的分子结构和独特的光电性质而广泛地应用于气体传感器、光电晶体管和太阳能电池等方面。有机薄膜中分子的排列和取向会显著影响分子器件的使用性能。本文评述CuPc分子及其衍生物在金属和石墨表面的自组织生长，和使用扫描隧道显微镜(STM)研究其分子结构和性质。CuPc在超高真空环境下容易形成有序单分子层，而在大气环境下生长分子膜较为困难。但是，通过增加烷烃链，或者与稳定性好的分子混合都能在大气下得到稳定的自组织形貌。Copper Phthalocyanine (CuPc) has been found extensive application in gas sensors, photoelectric transistors and solar cells due to its unique molecular structure and excellent photoelectrical properties. The molecular alignment and orientation in the organic layers affect the performance of devices to a great extent. This paper reviews the self-assembly growth of CuPc layers on metal and graphite surfaces and its molecular structures by scanning tunneling microscopy (STM). The ordered CuPc monolayer is readily obtained and well characterized in ultra-high vacuum; while the self-assembled growth of ordered molecular layer in ambient environment remains a challenge. Finally, we highlight the ways to achieve stable CuPc layers at ambient environment.
