However, whether they can be manufactured using printing technologies remained unexplored so far. In this work, we develop a new approach for the fabrication of ordered nanoporous microstructures based on supramolecular LCs using two-photon laser printing. In particular, we employ photo-cross-linkable hydrogen-bonded complexes, that self-assemble into columnar hexagonal (Colh) mesophases, as the base of our printable photoresist. The presence of photopolymerizable groups in the periphery of the molecules enables the printability using a laser. We demonstrate the conservation of the Colh arrangement and of the adsorptive properties of the materials after laser microprinting, which highlights the potential of the approach for the fabrication of functional nanoporous structures with a defined geometry. This first example of printable Colh LC should open new opportunities for the fabrication of functional porous microdevices with potential application in catalysis, filtration, separation, or molecular recognition. info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 9.5 2022 NANOSCIENCE & NANOTECHNOLOGY 27 / 107 = 0.252 2022 Q2 T1 MATERIALS SCIENCE, MULTIDISCIPLINARY 55 / 343 = 0.16 2022 Q1 T1 2.178 2022 Materials Science (miscellaneous) 2022 Q1 Nanoscience and Nanotechnology 2022 Q1 Medicine (miscellaneous) 2022 Q1 15.7 2022 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Concellón, Alberto Universidad de Zaragoza (orcid)0000-0002-8932-9085 Dong, Ruiqi Simmler, Mira Münchinger, Alexander Huck, Christian Tegeder, Petra Nirschl, Hermann Wegener, Martin Osuji, Chinedum O.
