They consist of two porphyrins that are each attached to a diphenylglycoluril\u2010based clip molecule via four ethyleneoxy spacers, and are linked together by a single alkyl chain using \u201cclick\u201d\u2010chemistry. Following a newly developed multistep synthesis procedure we report three of these double porphyrin cages, linked by spacers of different lengths, i.e. 3, 5, and 11 carbon atoms. The structures of the double porphyrin cages were fully characterized by NMR, which revealed that they consist of mixtures of two diastereoisomers. Their zinc derivatives are capable of forming sandwich\u2010like complexes with the ditopic ligand 1,4\u2010diazabicyclo[2,2,2]octane (<jats:bold>dabco<\/jats:bold>).<\/jats:p>","DOI":"10.1002\/ejoc.202001211","type":"journal-article","created":{"date-parts":[[2020,12,18]],"date-time":"2020-12-18T16:28:27Z","timestamp":1608308907000},"page":"7087-7100","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Double Porphyrin Cage Compounds"],"prefix":"10.1002","volume":"2020","author":[{"given":"Kathleen","family":"Stout","sequence":"first","affiliation":[{"name":"Institute for Molecules and Materials Radboud University  Heyendaalseweg 135 6525 AJ Nijmegen The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Theo P.
