Figure 4.The electronic structure characterization of aza-[5]-triangulene on Au(111). (a) A stacked line of dI/dVspectra recorded along the edge of an aza-[5]triangulene molecule on Au(111), as indicated in the inset image. (b) Spin-polarized DFT calculations for the singly positively charged molecule. Presented to the right of this are the calculated orbital densities (c)-(g) and CO tip dI/dVimages (both constant current and constant height, (h)-(q)) of an aza-[5]triangulene molecule recorded at voltages corresponding to the main features in the dI/dVspectra.
