In 1,1,2,2-tetrachloroethane-d2 , the 129 Xe NMR spectrum of the Xe@cryptophane-223 complex bearing seven acetate groups (Xe@1 complex) shows an unusually broad signal compared with that of its congeners (Chapellet, LL. et al. J. Org. Chem. 2015;80:6

Accepted Manuscript; International audience; Cryptophanes, cage-molecules constituted of aromatic bowls, are now well recognized as powerful xenon hosts in $^{129}$Xe NMR-based biosensing. In the quest of a dual probe that can be addressed only by NM
