Simple and complex lattices of N-alkyl fatty acid amides on a highly oriented pyrolytic graphite surface

STM investigations of three N-alkyl fatty acid amide molecules have been carried out to get information of their molecular arrangement on a highly oriented pyrolytic graphite surface. With variable positions of amide along the alkyl chain, complex lattices with different lattice constants were obser...

520 |a STM investigations of three N-alkyl fatty acid amide molecules have been carried out to get information of their molecular arrangement on a highly oriented pyrolytic graphite surface. With variable positions of amide along the alkyl chain, complex lattices with different lattice constants were observed. Besides the lattices with a repeat unit matching one or two molecular lengths, a lattice with a repeat unit corresponding to three molecular lengths was found. In addition, the portion of different lattices depends on the length of the shorter alkyl chain. DFT-D calculations point to interactions of antiparallel oriented dipoles due to the amide group, which are distance dependent and thus larger for shorter N-alkyl chains
