  The rapid development of functional graphene-like nanoribbons with
high-quality has become increasingly reliant on multiple nanofabrication
platforms while traditional methods are facing mounting limitations in this
regard. Consequently, the demand for novel techniques to explore and manipulate
graphene-like nanoribbons has surged. Herein, we report an on-surface synthesis
of graphene-like nanoribbons on pentacene/picene monomers via a series of
self-assembly and annealing on the one-dimensional(1D) Au(110) substrate. Our
scanning tunneling microscope(STM) research reveals that four-/eight- membered
rings are formed between adjacent molecules. Furthermore, we demonstrate the
technique to manipulate the pentacene dimer without breaking its structure by
operating an STM tip. Our results exhibit a possible platform for developing
next generation graphene-based quantum computing designs and a technique to
obtain multiple functional graphene-like nanoribbons with high-precision.
