CarolinaMagnetic and luminescent lanthanoid (Ln = Tb, Dy) 2D MOFs on functionalized siliconART-2025-145517The controlled deposition of organized molecular materials on technologically relevant substrates is crucial for the development of innovative magneto-optical devices. In this work, we report the growth of lanthanoid-based 2D metal–organic frameworks (MOFs) with formula unit [Ln(MeCOO)(PhCOO)2] (Ln = Dy, Tb) on Si(100) wafers functionalized by silanization. The thickness, morphology and composition of the grown material was assessed using a combination of ellipsometry, contact angle measurements, scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS). The on-surface grown terbium 2D MOFs exhibit green luminescence, like the bulk. Furthermore, chemisorbed Dy and Tb 2D MOFs retain a significant magnetic moment, as demonstrated by X-ray magnetic circular dichroism (XMCD) measurements conducted at the M4,5 edge of the two lanthanoids. Our work paves the way for the preparation of magneto-optical devices and organized arrays of single-molecule magnets (SMMs) and qubits on surfaces for high-density information storage and quantum computing applications.2025http://zaguan.unizar.es/record/16299710.1039/d5tc02447ahttp://zaguan.unizar.es/record/162997oai:zaguan.unizar.es:162997info:eu-repo/grantAgreement/ES/DGA/E12-23Rinfo:eu-repo/grantAgreement/ES/MCIU/PGC2018-098630-B-I00info:eu-repo/grantAgreement/ES/MICINN/PID2022-137764OB-I00info:eu-repo/grantAgreement/ES/MICINN/PID2022-138492NB-I00JOURNAL OF MATERIALS CHEMISTRY C (2025), [12 pp.]by-nchttps://creativecommons.org/licenses/by-nc/4.0/deed.esinfo:eu-repo/semantics/openAccess
