On-surface synthesis (OSS) is emerging as an extremely promising strategy for creating organic nanoarchitectures with atomic precision. To date, OSS has been particularly successful in synthesizing homogeneous one-dimensional graphene nanoribbons (GNRs) [1,2], but their functionalization, the realization of hybrid and heterostructures, and the extension to 2D nanostructures are yet three major challenges, with only a few examples of success [3]. Nevertheless, overcoming these challenges is crucial to unlock the full potential of GNRs in various application fields, such as nanoelectronics, gas sensing and energy storage.
Based on recent results from our group, which demonstrated the formation of lateral GNR heterostructures via interdigitation of ribbons with different band alignments [3], we now aim to push the complexity further by incorporating non-graphenoid components. This strategy enables the creation of multifunctional heterostructures that combine semiconducting GNR channels with tailored functional sites.
In this talk, I will present recent advances in the hierarchical OSS approach we have developed to realize these hybrid nanoarchitectures. The resulting multifunctional nanoarchitectures are expected to drive innovation in nanomaterials, particularly for real-devices applications.
