In order to find the reason why racemic and (M)-type 2, 13-bis(hydroxymethyl)-[7]thiaheterohelicene ([7]TH-diol) both form similar zig-zagged chain structures on the Au(111) surface observed by scanning tunneling microscopy (STM), in this work, we investigated the origin of the adsorption and aggretation behaviors for [7]TH-diol on graphene by using molecular dynamics (MD) simulation. Our MD simulations well reproduced the STM results. Moreover, we estimated the growth process of the self-assembled strucutres was traced from several molecules, and evaluated interactions between the molecules.
