It also has been supported by the European Commission through the fellowship H2020-MSCA-IF-2017 794885-SELFSENS. Herein, we present the syntheses of a novel coordination polymer (CP) based on the perylene-3,4,9,10-tetracarboxylate (pery) linkers and sodium metal ions. We have chosen sodium metal center with the aim of surmising the effect that the modification of the metal ion may have on the relative humidity (RH) experimental measurements of the material. We confirm the role of the ions in the functionalization of the deposited layer by modifying their selectivity towards moisture content, paving the way to the generation of sensitive and selective chemical sensors. 2022-04-21T11:52:27Z 2022-04-21T11:52:27Z 2022-02-21 info:eu-repo/semantics/article García-García, A.; Toral, V.; Quílez del Moral, J.F.; Galisteo Pretel, A.; Morales, D.P.; Salinas-Castillo, A.; Cepeda, J.; Choquesillo-Lazarte, D.; Bobinger, M.; Salmerón, J.F.; et al.
