To establish a unified on-surface synthetic method to generate higher acenes through undecacene and characterize their electronic properties.
Deposited partially saturated precursor molecules onto surfaces and converted them into parent acenes via scanning probe tip manipulation and thermal annealing.
Imaged the chemical structures of generated acenes using high-resolution non-contact atomic force microscopy.
Measured transport gap changes across varying lengths of fused benzene rings using scanning tunneling spectroscopy.
Successfully synthesized and directly visualized a series of higher acenes, including the previously unreported eleven-ring undecacene.
Demonstrated reliable conversion using both thermal on-surface annealing and local atomic manipulation with microscope tips.
Observed a systematic evolution of the transport gap corresponding to the increasing number of linearly fused benzene rings.
