The electrophilic substitution of 25,27-dipropoxy-26,28-dinosyloxycalix[4]arene leads exclusively to the para-substitution of the alkylated phenol rings, while in the next step, the protecting nosyl group can be easily removed using a basic hydrolysis. The overall process yields dialkoxycalix[4]arenes with the substitution on the alkylated rings—the substitution pattern, which is complementary to the

Synthesis of a previously unobtainable calixarene building block eliminates disorder both within and between template-assembled nanotubes. This allows for elucidation of the role of all co-crystallised components and observation of the key intermolecular interactions in the resulting system.
