Table 3.
Comparison between the normalized intensity of the π1* resonance (with respect to the height of the absorption edge) in the C K-edge NEXAFS spectra of the target SAMs and portion of the benzene ring carbon atoms in the respective molecules (%). The ratio of both values, i. e., the normalized intensity of the π1* resonance corrected for the portion of the benzene ring carbon atoms in the respective molecules, is given in the third column.
| SAM | π1* Intensity / a.u. | Portion of benzene ring carbon atoms (%) | π1* Intensity / a.u. (corrected for the portion of the benzene ring carbon atoms) |
|---|---|---|---|
| PTT | 2.6 | 66 | 3.93 |
| BPTT | 3.3 | 80 | 4.125 |
| PTET | 1.2 | 50 | 2.4 |
| BPTET | 1.5 | 66 | 2.27 |
| BPT | 3.8 | 100 | 3.8 |
