{"publication":"Chemistry of Materials","issue":"16","abstract":[{"text":"We report the synthesis, structural elucidation, and establishment of structure−property relationships for two metal−organic frameworks (MOFs), [M(OH)(H2BPD)]·xH2O (M = Al3+, Ga3+, x = 11–13), denoted as M-CAU-67, employing the ditopic linker molecule N,N′-4,4′ bipiperidine bis(methylenephosphonic acid) (H4BPD). The title compounds can be synthesized on a milligram scale under hydrothermal conditions, while gram-scale synthesis was realized under reflux conditions. Single-crystal X-ray diffraction (SCXRD) revealed an isoreticular, expanded MIL-91 type structure, representing a rare case of isoreticular expansion in porous metal phosphonates. The framework structure was confirmed by Rietveld refinement against powder X-ray diffraction (PXRD) data and further validated by solid-state NMR spectroscopy (31P MAS, 27Al 3Q MAS). Solvent-exchange experiments and variable-humidity/temperature PXRD data revealed high framework flexibility. The compounds show permanent microporosity and a complex, polarity- and size-dependent sorption behavior toward gases and vapors.","lang":"eng"}],"date_created":"2026-10-01T14:16:40Z","department":[{"_id":"35"},{"_id":"2"},{"_id":"307"}],"type":"journal_article","author":[{"last_name":"Theissen","first_name":"Jennifer","full_name":"Theissen, Jennifer"},{"full_name":"Radke, Marvin","first_name":"Marvin","last_name":"Radke"},{"full_name":"Mangelsen, Sebastian","first_name":"Sebastian","last_name":"Mangelsen"},{"last_name":"Derveaux","first_name":"Elien","full_name":"Derveaux, Elien"},{"full_name":"Narváez Adams, Roberth Mateo","last_name":"Narváez Adams","first_name":"Roberth Mateo"},{"full_name":"Wagner, Tobias","last_name":"Wagner","first_name":"Tobias"},{"last_name":"Lopau","first_name":"Jasper","full_name":"Lopau, Jasper"},{"full_name":"Näther, Christian","first_name":"Christian","last_name":"Näther"},{"full_name":"Nelle, Christian","first_name":"Christian","last_name":"Nelle"},{"first_name":"Jörn","last_name":"Struve","full_name":"Struve, Jörn"},{"first_name":"Felix","last_name":"Steinke","full_name":"Steinke, Felix"},{"full_name":"Gándara Loe, Jesús","last_name":"Gándara Loe","first_name":"Jesús"},{"full_name":"Gys, Nick","last_name":"Gys","first_name":"Nick"},{"full_name":"Hauffman, Tom","first_name":"Tom","last_name":"Hauffman"},{"orcid":"0000-0003-1711-2722","last_name":"Tiemann","first_name":"Michael","full_name":"Tiemann, Michael","id":"23547"},{"last_name":"Tielens","first_name":"Frederik","full_name":"Tielens, Frederik"},{"full_name":"Adriaensens, Peter","first_name":"Peter","last_name":"Adriaensens"},{"last_name":"Henke","first_name":"Sebastian","full_name":"Henke, Sebastian"},{"last_name":"Marchal","first_name":"Wouter","full_name":"Marchal, Wouter"},{"last_name":"Ameloot","first_name":"Rob","full_name":"Ameloot, Rob"},{"first_name":"Norbert","last_name":"Stock","full_name":"Stock, Norbert"}],"publication_identifier":{"issn":["0897-4756","1520-5002"]},"title":"Isoreticular Expansion in Porous Aluminum(III) andGallium(III) Phosphonates: Synthesis, Structure, and Properties","year":"2026","intvolume":"        38","date_updated":"2026-10-01T14:20:02Z","publication_status":"published","language":[{"iso":"eng"}],"main_file_link":[{"open_access":"1"}],"doi":"10.1021/acs.chemmater.6c01336","citation":{"ama":"Theissen J, Radke M, Mangelsen S, et al.
