Silver cations were incorporated from an aqueous AgNO3 sub-phase of Langmuir films of 4,4'-(1,4-phenylenebis(ethyne-2,1-diyl))dibenzoic acid upon the transference of these films onto a metallic substrate. Subsequent irradiation of the silver-ion functionalized Langmuir–Blodgett films with 254 nm light results in the photoreduction of silver cations to produce metallic silver nanoparticles, which are distributed over the organic monolayer and exhibit a surface coverage as large as 76% of the monolayer surface. Electrical properties of these metal/monolayer/metal devices were determined by recording I–V curves, which show a sigmoidal behaviour indicative of well-behaved junctions free of metallic filaments and short-circuits. The integrity of the organic monolayer upon the irradiation process and formation of the silver top-contact electrode has also been demonstrated through cyclic voltammetry experiments. info:eu-repo/grantAgreement/ES/CSIC/10-4E-805 info:eu-repo/grantAgreement/ES/DGA/E54 info:eu-repo/grantAgreement/ES/MINECO/CSD2010-00024 info:eu-repo/grantAgreement/ES/MINECO/CTQ2012-33198 info:eu-repo/grantAgreement/ES/MINECO/CTQ2012-50187-EXP info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 5.256 2016 PHYSICS, APPLIED 18 / 147 = 0.122 2016 Q1 T1 MATERIALS SCIENCE, MULTIDISCIPLINARY 36 / 275 = 0.131 2016 Q1 T1 1.825 2016 Materials Chemistry 2016 Q1 Chemistry (miscellaneous) 2016 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Ballesteros, Luz M.
