The SCSD analysis technique can be adapted to characterizing the symmetry concerns of ultrashort nanotubes, compounds such as cycloparaphenylenes (CPP) which, while not what one would think of as 'rigid groups' are rigidified by annular strain. Nanotubes have been simulated which exhibit morphological changes, but only a few crystallized examples of low-MW oligomers are available. We have included exemplar analyses of [6]CPP (~D6h), octabenzo-[4]CPP (~D4h) and cyclo-2,7tetra(4,5,9,10-tetrahydropyrene) (i.e., octaethylene- [8]CPP, ~D4h) (Fig. ). In each case, we can directly observe the prominence of the alternating aryl-aryl non-coplanarity which deform the solidstate structure, and some level of ovaloid squashing, but these take on different symmetry characters in each case. In [4], this is by B2u (to D2h) for the rotation, and B1g for the (barely observed) squash.
