In addition to the geometric distortion of CoPc upon binding to the SWCNT, we observe a shift in the N 1s indicating electronic structure distortion. DFT predicts 4 degenerate N 1s orbitals at -381.16 eV below the vacuum energy. Forcing the complex into the curved geometry breaks the degeneracy of the N 1s orbitals. Specifically, the 4 orbitals now range from -381.44 eV to -381.36 eV (0.08 eV variation). The N 1s orbitals are also stabilized in the curved complex by an average of -0.24 eV, indicating increased binding energy as observed in experiment (Fig. ).
