Abstract Semiconductor molecular-material thinfilms of [6,13-Ac 2 -5,14-Me 2 -[14]-4,6,11,13-tetraenato-1,4,8,11-N 4 ] and the bidentate amines 1,4-diaminebutane, 1,12-diaminedodecane and 2,6-diamineanthraquinone have been prepared by vacuumthermalevaporation on corning glass substrates and crystalline silicon wafers. The films thus obtained were characterized by infrared (FTIR), ultraviolet–visible
