摘　　要：The self-assembled structures of 4, 4′-dionoyl-2, 2′-dipyridyl and its co-adsorption with stearic acid on highly oriented pyrolytic graphite (HOPG) have been studied by the scanning tunneling microscopy (STM). As a result, 4,4′- dionoyl-2,2′-dipyridyl forms a planar trans conformation in two cases, and through the co-adsorption with stearic acid, 4, 4′-dionoyl-2,2′-dipyridyl and stearic acid form a well-or- dered nanostructure.The self-assembled structures of 4, 4′-dionoyl-2, 2′-dipyridyl and its co-adsorption with stearic acid on highly oriented pyrolytic graphite (HOPG) have been studied by the scanning tunneling microscopy (STM).
