Abstract

Abstract: Electrochemical scanning tunneling microscopy(EC-STM) and cyclic voltammetry were employed to investigate the self-assembled structure of a new heteroatom-bridged calix(hetero)aromatics, tetraazacalixarenetrizaine derivative on Au(111) surface. High-resolution STM images reveal that the molecules form long-range ordered monolayers. Moreover, the molecule adopts a 1,3-alternate conformation. Two triazine rings lie flatly on Au(111) surface, while two phenyl rings were tilted. This could be attributed to a balance between intermolecular and molecule-substrate interactions.

Key words: Scanning tunneling microscopy, Cyclic voltammetry, Heteroatom-bridged calix(hetero)aromatic hydrocarbon, Self-assembly
