Realizing reversed conductance decay is an important step toward making long and highly conducting molecular wires. Recent work has shown that one-dimensional topological insulators (1D TIs) can exhibit reversed conductance decay due to their nontrivial edge states. The Su–Schrieffer–Heeger (SSH) model for 1D TIs relates to the electronic structure of these isolated molecules but not their electron transport properties as single-molecule junctions. Herein, we use a tight-binding approach to demonstrate that polyacetylene and other diradicaloid 1D TIs show a reversed conductance decay at the short chain limit. We explain these conductance trends by analyzing the impact of the edge states in these 1D systems on the single-molecule junction transmission. Additionally, we discuss how the self-energy from the electrode-molecule coupling and the on-site energy of the edge sites can be tuned to create longer wires with reversed conductance decays.","lang":"eng"}],"intvolume":"        13","quality_controlled":"1","day":"11","status":"public","main_file_link":[{"open_access":"1","url":"https://doi.org/10.26434/chemrxiv-2022-b1fh9-v3"}],"month":"10","OA_type":"green","oa":1,"extern":"1","doi":"10.1021/acs.jpclett.2c02812","volume":13,"year":"2022","external_id":{"pmid":["36219846"]}}
