(a) Variable temperature (VT) 1H NMR spectra (500 MHz, CD2Cl2) of 22+ in the region of the triazolium protons (HTru, HTrc). (b) VT 1H NMR spectra (500 MHz, CD2Cl2) of 12+ in the regions of the triazolium protons (HTru, HTrc; left) and of the methylene protons in the pyrenyl tether of the macrocycle, adjacent to the dioxybenzene unit (HPya, HPyb; right). See Scheme 1 and SI for proton labeling.
