    • The observation of an intramolecular hydrogen bond was tentatively proposed by Gross et al. in the study of the organic compound cephalandole A (8).

    • note
    • The measured bond length may involve the amplification effect of CO on the tip apex, as discussed in (11). It should also be noted that the expected bending of X-H⋯Y was not resolved in all of the hydrogen bonds shown in Fig. 2, A and B. The exact mechanism was not understood.

    • note
    • We found that it is difficult to obtain a high-resolution AFM image on this specific type of 8-hq dimer compared with single molecules or other molecular aggregates. These dimers often accidentally dislocate during AFM imaging, indicating a weaker interactions between the molecules and the substrate. We suggested that the formation of two hydrogen bonds in the dimer weaken the binding interaction of -OH and N of 8-hq to the metal substrate. Note that the optimal imaging parameters for this dimer (see the Fig. 3A legend) are different from those used for other molecular clusters.
