Abstract
Inclusion phenomena of the solvents such as hexane, benzene, and dichloromethane in either the crystals or glassy states of the armed-1,4,8,12-tetrazacyclopentadecanes were observed, whereas only few inclusion was found in the armed 1,4,8,11- tetraazacyclotetradecanes. As further examples of undesigned inclusion hosts, the 1:2 adduct, obtained by Diels-Alder reaction of [2.2]paracyclophane with 4-phenyl-1,2,4-triazoline-3,5-dione, along with the 1:2 adducts fiom 5-cyano- 1,4-diphenylpyridazino[4.5-a]- indolizines and dimethyl acetylenedicarboxylate (DMAD) are described.
