The Spinning Triazolophane

This triazolophane was constructed first by truncating the phenylene's substituents to hydrogens. Second, even though triazolophanes are selective for chloride, bromide was used in its place because it is slightly larger (ionic radius of ~1.9 Å instead of ~1.7 Å) thus allowing the red printed bromide atom to ride higher than the plane of the receptor (vdW radii for C, H, N = 1.7, 1.1, 1.55 Å). The net result is a spinning top that also serves as a 3D molecular model!
