To this end, our work provides a robust methodology for the preparation of CCMoid-based active surfaces with a fluorescent response and reusability. The covalent immobilization of the CCMoid is obtained by the reaction of the acidic groups of PA and the imidazole ends of the previously functionalized substrates. In this way, fluorescent patterned surfaces of PA, whose emission could be observed in the visible region thanks to the pyrene groups of the CCMoid, were obtained using microcontact printing. In addition, the coordination of BF3 molecules (in solution and in gas phase) with the keto–enol moiety of the PAs anchored on the surfaces has been analyzed. The ability of BF3 to modify the optical properties of the CCMoids-based surfaces, leading to emissions in the near-IR, has been identified as a fast and reversible process. Such ability is intrinsic to the final coordinated system and not to other boron-based molecules, providing unique response and sensing surfaces. info:eu-repo/grantAgreement/ES/AEI/CEX2023-001263-S info:eu-repo/grantAgreement/ES/MICINN/CEX2021-001202-M info:eu-repo/grantAgreement/ES/MICINN/PID2019-1108794GB-I00 info:eu-repo/grantAgreement/ES/MICINN/PID2021-122464NB-I00 info:eu-repo/grantAgreement/ES/MICINN/PID2023-151929NB-I00 info:eu-repo/semantics/openAccess by https://creativecommons.org/licenses/by/4.0/deed.es info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Díaz-Torres, Raúl Gómez-Coca, Silvia Roubeau, Olivier (orcid)0000-0003-2095-5843 Díaz-Cruz, José Manuel Aliaga-Alcalde, Núria González-Campo, Arántzazu 17, 13 (2025), 20383-20393 ACS appl. mater. interfaces ACS applied materials & interfaces 1944-8244 8560941 http://zaguan.unizar.es/record/153147/files/texto_completo.pdf Versión publicada 3239828 http://zaguan.unizar.es/record/153147/files/texto_completo.jpg?subformat=icon icon Versión publicada oai:zaguan.unizar.es:153147 articulos driver 2025-10-17-14:36:40 ARTICLE
