Fig 5 Effect of different tip modifications on imaging (A, B) constant-height NC-AFM images of a dibenzo (cd, n) naphtho (3, 2, 1, 8-pqra) perylene (DBNP) molecule on NaCl (2ML)/Cu (111) with CO tip and Xe tip, respectively; (C, D) constant-height NC-AFM images of a dibromoanthracene (DBA) molecule on NaCl (2ML)/Cu (111) with a Cl tip and Br tip, respectively37; (E) vertical force cut of the 3D NC-AFM data set on the striped Cu (110)-(2 × 1) O added-row reconstruction. The inset is the structural models of O terminated Cu tip. (F) constant-height NC-AFM image recorded on a single dicoronylene (DCLN) adsorbed on Cu (110) with an O terminated Cu tip38
