Electrochemical measurements using [Ru(NH3)(6)](3+), [Fe(CN)(6)](3-), and ferrocenylmethanol [Fe((5)-C5H4CH2OH)((5)-C5H5)] redox probes indicate that the alkynyl C-Au contacted monolayer of 1 presents a relatively low barrier for electron transfer. This contrasts with monolayer films on gold of other oligo(phenylene ethynylene) derivatives of comparable length and surface coverage, but with different contacting groups. Additionally, a low voltage transition (V-trans = 0.51 V) from direct tunneling (rectangular barrier) to field emission (triangular barrier) is observed. This low transition voltage points to a low tunneling barrier, which is consistent with the facile electron transport observed through the C-Au contacted self-assembled monolayer of 1. 000147985 536__ $$9info:eu-repo/grantAgreement/ES/DGA/E31-17R$$9info:eu-repo/grantAgreement/ES/DGA/E47-17R$$9info:eu-repo/grantAgreement/EC/FP7/607602/EU/Hierarchical Self Assembly of Polymeric Soft Systems/SASSYPOL$$9info:eu-repo/grantAgreement/ES/MINECO-FEDER/MAT2016-78257-R 000147985 540__ $$9info:eu-repo/semantics/openAccess$$aAll rights reserved$$uhttp://www.europeana.eu/rights/rr-f/ 000147985 590__ $$a6.895$$b2019 000147985 591__ $$aMATERIALS SCIENCE, MULTIDISCIPLINARY$$b50 / 314 = 0.159$$c2019$$dQ1$$eT1 000147985 591__ $$aNANOSCIENCE & NANOTECHNOLOGY$$b25 / 103 = 0.243$$c2019$$dQ1$$eT1 000147985 591__ $$aCHEMISTRY, MULTIDISCIPLINARY$$b28 / 176 = 0.159$$c2019$$dQ1$$eT1 000147985 591__ $$aPHYSICS, APPLIED$$b23 / 154 = 0.149$$c2019$$dQ1$$eT1 000147985 592__ $$a2.18$$b2019 000147985 593__ $$aNanoscience and Nanotechnology$$c2019$$dQ1 000147985 593__ $$aMaterials Science (miscellaneous)$$c2019$$dQ1 000147985 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/acceptedVersion 000147985 700__ $$aGonzalez-Orive, A 000147985 700__ $$aMarques-Gonzalez, S 000147985 700__ $$0(orcid)0000-0001-9193-3874$$aMartin, S$$uUniversidad de Zaragoza 000147985 700__ $$aNichols, R.J 000147985 700__ $$0(orcid)0000-0001-9866-6633$$aSerrano, J.L$$uUniversidad de Zaragoza 000147985 700__ $$aLow, P.J 000147985 700__ $$0(orcid)0000-0002-4729-9578$$aCea, P.$$uUniversidad de Zaragoza 000147985 7102_ $$12013$$2765$$aUniversidad de Zaragoza$$bDpto.
