Self-ordered monolayers of fullerene derivatives assembled via bimolecular building block
2006
Abstract We reported the design and fabrication of a C 60 derivative with a uracil-like unit (U-C 60 ), to form a bi-molecular building block with a C 60 derivative with a 2,6-bis (acylamino) pyridine unit (DAP-C 60 ) by complementary trident hydrogen-bonding array. By pre-organizing these two fullerene derivatives in solution, bimolecular blocks were formed via robust and highly directional trident hydrogen-bonding recognition between DAP-C 60 and U-C 60 . Then, the bimolecular blocks were deposited on highly ordered pyrolytic graphite (HOPG). The structure of the monolayer was characterized using a scanning tunneling microscope. Well-ordered monolayer composed of the two fullerene derivatives of DAP-C 60 and U-C 60 was observed and the structure of the monolayer was modeled.
