Synthesis of a Naphthodiazaborinine and Its Verification by Planarization with Atomic Force Microscopy

Aiming to study new motifs, potentially active as functional materials, we performed the synthesis of a naphthodiazaborinine (the BN isoster of the phenalenyl anion) that is bonded to a hindered di-ortho substituted aryl system (9-anthracene). We used atomic force microscopy (AFM) and succeed in both, the verification of the original non-planar 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 be probed with AFM directly.
