Figure 5: Time-dependent characterisation of the synthesis of octahedron 2.
From: Assembled molecular face-rotating polyhedra to transfer chirality from two to three dimensions
(a) Selected HPLC spectra at certain time intervals. The components of the intermediates were determined by mass spectrometry. (b) Kinetic profile of the synthesis of octahedron 2 (1.6 mM at 298 K, absorption monitored at 325 nm), showing the consumption of truxene and the formation of three octahedral diastereomers. The formation and disappearance of the intermediates with the [1+1], [1+2], [3+3], [3+4] and [4+5] components can also be tracked. The percentages were evaluated from the HPLC peak areas. (c) Time-dependent CD intensities at 340 nm normalised by the intensity at 24 h.
