A strategic combination of supramolecular and interfacial chemistry may serve to build a well‐organized molecular network, enabling the subsequent location of target molecules on specific positions of a surface. A supramolecular complex (compound 1) comprised of a melamine unit forming hydrogen bonds with dendritic arms terminated in a coumarin unit is utilized, which readily undergoes photodimerization. The research demonstrates the formation of well‐organized Langmuir films of compound 1 which can be transferred on substrates at low surface pressures adopting a lying‐flat orientation. Upon irradiation of the pristine films at 365 nm the coumarin units undergo photo‐cross linking, leading to the formation of a compact photo‐crosslinked film. Incubation of these photo‐crosslinked films in a solution containing 1‐hexanethiol results in the withdrawal of the melamine and the chemisorption of two thiol molecules per each melamine unit. The nanopores created by the removal of the melamine core are attributed to the disruption of hydrogen bonds in compound 1 by the thiols. This precisely defined molecular network holds significant promise as a template for orchestrating the arrangement of functional materials on surfaces. info:eu-repo/grantAgreement/ES/DGA/E31-23R info:eu-repo/grantAgreement/ES/DGA/E47-23R info:eu-repo/grantAgreement/ES/MICINN-FEDER/PID2021-122882NB-I00 info:eu-repo/grantAgreement/ES/MICINN/PGC2018-097583-I00 info:eu-repo/grantAgreement/ES/MICINN/PID2019-105881RB-I00 info:eu-repo/grantAgreement/ES/MICINN/PID2022-141433OB-I00 info:eu-repo/grantAgreement/ES/MICINN/RYC2021-031154-I info:eu-repo/grantAgreement/EUR/MICINN/TED2021-131318B-I00 info:eu-repo/semantics/openAccess by https://creativecommons.org/licenses/by/4.0/deed.es 4.4 2024 CHEMISTRY, MULTIDISCIPLINARY 79 / 239 = 0.331 2024 Q2 T2 MATERIALS SCIENCE, MULTIDISCIPLINARY 174 / 461 = 0.377 2024 Q2 T2 1.154 2024 Mechanics of Materials 2024 Q1 Mechanical Engineering 2024 Q1 9.6 2024 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Concellón, Alberto Universidad de Zaragoza (orcid)0000-0002-8932-9085 Cardona, Teresa Zuccheri, Giampaolo Martín, Santiago Universidad de Zaragoza (orcid)0000-0001-9193-3874 Serrano, José L.
