Figure 2: Molecular structure and characterisation of octahedra 1.
From: Assembled molecular face-rotating polyhedra to transfer chirality from two to three dimensions
(a) Molecular structure of the octahedron (CCCC)-1. (b) Single-crystal structure of the co-crystal of (CCCC)-1 and (AAAA)-1 (hydrogen atoms and butyl groups are omitted for clarity). (c) Chiral HPLC spectrum contains two peaks corresponding to (AAAA)-1 and (CCCC)-1 in a 1:1 ratio. The absorbance for all octahedra was recorded at 325 nm. (d) Experimental and (ZINDO/S)-predicted (the insert) CD spectra of (AAAA)-1 (red), (CCCC)-1 (blue), and the unseparated racemic mixture (black) in hexane.
