Abstract

Improved synthetic procedures were developed for C-alkyl substituted calix[4]resorcinarenes, pyrimidine-5-boronic acid, 5,5'-bipyrimidine, 5-((trimethylsilyl)ethynyl)pyrimidine, 1,2-bis(5'-pyrimidyl)ethyne, and pyrimidine-5-carboxylic acid. Studies on the crystal packing of nano-capsules composed of C-alkyl calix[4]resorcinarenes and alcohol ligands were performed. C-Alkyl chains between capsules interacted with each other through van der Waals forces, packing in a predictable manner. C-Alkyl substituted calix[4]resorcinarenes also formed capsules in chain-linked hydrogen bonded networks with 5,5'-bipyrimidine and 1,2-bis(5'-pyrimidyl)ethyne. In these chain-linked hydrogen bonded capsules, C-alkyl chains interacted with each other through van der Waals forces, causing the capsule networks to pack together predictably.
