The electrical conductance of the Mylar–PEDOT : PSS|OPEH|Graphene structure was determined by conductive probe atomic force microscopy (c-AFM), sampling various regions across the surfaces of multiple devices. All registered I–V curves (sampling size ∼150 tests) give a sigmoidal response, consistent with through molecule conductance and ruling out the presence of direct electrode contacts or short-circuits. The demonstration of the combined use of Mylar-supported PEDOT : PSS and graphene as alternative electrode materials to conventional metal thin film electrodes in large-area molecular junctions opens avenues to enable flexible and transparent molecular (opto)electronic devices.2023http://zaguan.unizar.es/record/13548910.1039/d3tc02237dhttp://zaguan.unizar.es/record/135489oai:zaguan.unizar.es:135489info:eu-repo/grantAgreement/ES/AEI/AEI PID2022-14143300B-I00info:eu-repo/grantAgreement/ES/AEI/RYC-2016-21412info:eu-repo/grantAgreement/ES/DGA/E31-23Rinfo:eu-repo/grantAgreement/ES/MCIU/PID2019-105881RB-I00info:eu-repo/grantAgreement/ES/MCIN/AEI/10.13039/501100011033info:eu-repo/grantAgreement/EUR/MICINN/TED2021-131318B-I00JOURNAL OF MATERIALS CHEMISTRY C 12, 4 (2023), 1325-1333All rights reservedhttp://www.europeana.eu/rights/rr-f/info:eu-repo/semantics/embargoedAccess
