a, Thread (E-diastereomer); b, E-1; c, 1 at the 350 nm photostationary state (dba-Z-1:mba-Z-1:E-1, 38:21:41); d, 1+benzil (10 equiv.) at the 350 nm photostationary state (dba-Z-1:mba-Z-1:E-1, 32:48:20). Resonances are coloured and the lettering assigned according to Fig. 1: macrocycle, red; occupied dba binding site, dark blue; unoccupied dba binding site, light blue; occupied mba binding site, dark green; unoccupied mba binding site, light green. The overlapping aromatic ring signals above 7.2 p.p.m. are not distinguished in this way. Residual non-deuterated solvents are shown in light grey (the signal at 5.5 p.p.m. is CH2Cl2).
