Intermixing behaviors of PCBM with CuPc on Au(111) surface
The behavior of phenyl-C-61-butyric acid methyl ester (PCBM) and copper-phthalocyanine (CuPc) on a Au (111) surface was investigated using scanning tunneling microscopy (STM). When CuPc was deposited in addition to PCBM it entered and disturbed the regularly spaced double row superstructure of the PCBM molecules. PCBM intermixed with CuPc to form a new square shaped superstructure that consisted of six to eight PCBM molecules with a CuPc molecule in its center. The intermixing of these materials that was observed indicated that they possessed an attractive interaction. (C) 2016 Elsevier B.V. All rights reserved.
