Fig. 3: Measurement of the unidirectionality.
Top: graphical representation of the positional exchange of the deuterium-labelled CBPQT4+ and CBPQT4+ rings on the loop after one redox cycle. Bottom: partial 1H NMR (600 MHz, CD3COCD3, 298 K) spectra of [Dn]-[3]CMM•13PF6 with proton assignments before (left) and after (right) one electrically driven redox cycle. Numbers under peaks indicate relative integrals. ppm, parts per million.
