Extended Data Fig. 3: 31P{1H} NMR spectra from competition experiments of 1, 2a and TPO.
From: Redox-switchable carboranes for uranium capture and release
a, 31P{1H} NMR spectrum of 2.0 equiv. 1 with 1.0 equiv. UO2Cl2(TPO)2 in DCM-d2. Relative integrations are shown in red. b, 31P{1H} NMR spectra of in situ reactions of 1.0 equiv. 2a with 1.0 equiv. UO2Cl2(TPO)2 in DCM-d2. Rapid precipitation of a yellow solid was observed. Top, 31P{1H} NMR spectrum of the DCM-d2 supernatant. An unknown byproduct at 47 ppm is observed. Bottom, 31P{1H} NMR spectrum of the filtrate dissolved in PC with a DCM-d2 capillary tube.
