Synthesis of a Naphthodiazaborinine and Its Verification by Planarization with Atomic Force Microscopy ; DOI: 10.1021/acsnano.6b01484 URL: http://pubs.acs.org/doi/abs/10.1021/acsnano.6b01484 Filiació URV: SI ; Aiming to study new motifs, potentially active as functional materials, we performed the synthesis of a naphthodiazaborinine (the BN isostere of the phenalenyl anion) that is bonded to a hindered di-ortho-substituted aryl system (9-anthracene). We used atomic force microscopy (AFM) and succeeded in both the verification of the original nonplanar structure of the molecule and the planarization of the skeleton by removing H atoms that cause steric hindrance. This study demonstrated that planarization by atomic manipulation is a possible route for extending molecular identification by AFM to nonplanar molecular systems that are difficult to probe with AFM directly.
