para-Acylcalix[n]arenes: from molecular to macroscopic assemblies

Chemical Communications Pub Date: 2008-03-20 DOI: 10.1039/B717495K

Abstract

The para-acylcalix[n]arenes possess a very rich capacity to self-assemble into a wide variety of structures and sizes ranging from molecular assemblies through dimeric capsules, molecular sheets to nanoparticles. All these assemblies are capable of taking guest molecules and in the process of this inclusion discrete nanoscopic reaction vessels may be formed for photochemistry. Interestingly this uptake of quite large organic molecules occurs in the bulk in non-porous crystals without loss of crystallinity. At the air–water interface either as Langmuir monolayers or as colloidal suspensions the para-acylcalix[n]arenes show interaction with ionic species. The extension from para-acylcalix[4]arenes to para-acylcalix[8]arenes is in its infancy but already there is much promise for novel assemblies to be found.
