ABSTRACTWe studied ultrathin layers of 𝑛 cyanobiphenyl (𝑛 = 5,6,7,8) mesogene moleculesforming thin films on a graphene plane using molecular dynamics simulations in a wide temperaturerange (220 420 K). Each modeled ensemble was heated to the maximum temperature andthen cooled (reverse procedure). We calculated the second rank order parameter as a measureof the molecular order of mesogene molecules and we discuss the distribution of angles betweenthem and the global sample director.
