| 英文摘要 | self-assembled structures of alkoxylated benzo[ c] cinnoline derivatives prepared on highly oriented pyrolytic graphite at room temperature from their solutions in solvents such as 1-phenyloctane, toluene, and 1-octanol were studied by scanning tunneling microscopy. the alkoxy chain length markedly affected the molecular conformations in 2-dimensional assemblies of these derivatives. long-chain derivatives adopted the trans conformations more often than cis, whereas short-chain derivatives took exclusively the cis conformations in the self-assembled monolayers (sams). for the derivatives of intermediate chain lengths, polymorphism existed, with four molecular conformations identified experimentally. experimental evidence substantiated the formation of chiral sam structures at the surface, which can be explained by the conformations of the molecules. the chirality was also affected by the chain length of the molecules. a simple method analyzing the angles between different domains in the sams was used to identify the molecular conformations and to predict their relative structures. |
