Here, we investigate whether a triptycene\u2010based tripodal platform can effectively decouple photoactive units from metallic and nonmetallic surfaces in Langmuir\u2013Blodgett (LB) films. Four structurally distinct photoswitches were incorporated into a common tripodal scaffold and assembled into organized monolayers at the air\u2013water interface, followed by transfer onto quartz and gold substrates. Comprehensive characterization confirms the formation of homogeneous, monomolecular films with controlled thickness (\u223c2\u00a0nm) and reproducible surface coverage. UV\u2013vis spectroscopy reveals that the photochemical response of surface\u2010bound systems closely resembles that observed in solution, with comparable switching behavior and thermal kinetics on both substrates. Notably, no systematic differences are observed between metallic and nonmetallic surfaces, demonstrating effective electronic decoupling by the tripodal architecture. In contrast, the azobenzene\u2010containing system exhibits asymmetric switching behavior governed by intermolecular packing within the monolayer, rather than substrate interactions. These findings establish tripodal molecular platforms as a robust strategy for preserving intrinsic photoswitch functionality in surface\u2010confined environments and provide key design principles for photoswitchable interfaces.<\/jats:p>","DOI":"10.1002\/chem.71613","type":"journal-article","created":{"date-parts":[[2026,8,27]],"date-time":"2026-08-27T15:01:50Z","timestamp":1787842910000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Triptycene\u2010Based Tripodal Molecular Platforms: A Comparative Study of Photoswitchable Langmuir\u2013Blodgett Films on Metallic and Nonmetallic Surfaces"],"prefix":"10.1002","author":[{"given":"Eva","family":"Kaletov\u00e1","sequence":"first","affiliation":[{"name":"Institute of Organic Chemistry and Biochemistry of the Czech Academy of Sciences  Prague Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Katarina Majerov\u00e1","family":"Varga","sequence":"additional","affiliation":[{"name":"Institute of Organic Chemistry and Biochemistry of the Czech Academy of Sciences  Prague Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carina Santos","family":"Hurtado","sequence":"additional","affiliation":[{"name":"Institute of Organic Chemistry and Biochemistry of the Czech Academy of Sciences  Prague Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guillaume","family":"Bastien","sequence":"additional","affiliation":[{"name":"Institute of Organic Chemistry and Biochemistry of the Czech Academy of Sciences  Prague Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Milan","family":"Ma\u0161\u00e1t","sequence":"additional","affiliation":[{"name":"Institute of Organic Chemistry and Biochemistry of the Czech Academy of Sciences  Prague Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6857-4324","authenticated-orcid":false,"given":"Zden\u011bk","family":"Bastl","sequence":"additional","affiliation":[{"name":"J.
