Description

Self-assembled monolayers of a series of tetraalkoxyl-substituted octadehydrodibenzo[12]annulenes (DBAs) possessing butadiyne linkages were studied by means of scanning tunnelling microscopy at the liquid/graphite interface. The purpose of this research is both to investigate the structural variation of 2D monolayers and to assess a possibility for peri-benzopolyacene formation by two-dimensionally controlled polymerization on a surface. As a result, the formation of porous, linear, and lamella structures, were observed by changing the alkyl chain length and the solute concentration. Even though the closest interatomic distance between the diacetylenic units of the DBAs in the lamella structure is slightly larger compared to the typical distances necessary for topochemical polymerization, the reactivity toward external stimuli was investigated. Unfortunately, no evidence for polymerization of the DBAs on the surface was observed. The present results indicate the necessity for further designing a suitable system for the on-surface construction of structurally novel conjugated polymers.
