Supramolecular chemistry has received much attention because of the specific molecular interaction and the unique molecular recognition under inclusion phenomena between host and guest species. Many researches on host-guest interaction were done for macrocyclic compounds such as crown ether, cyclodextrin , calixarenes, and their derivatives. In previous, our group reported N,N-bis(2-hydroxybenzyl)alkylamines obtained from a single-time ring opening reaction of benzoxazine with phenol derivatives (Laobuthee, 2002). Theoretically, N,N-bis(2-hydroxybenzyl)alkylamine derivatives are the weak acid owing to the hydroxyl of phenol units. Considering the basic structure of N,N-bis(2-hydroxybenzyl) alkylamine, there are many possibilities to proceed the reaction through hydroxyl group such as esterification and etherification. However, molecular recognition under inclusion phenomena of those derivatives by esterification was rarely occurred. The present work, thus, aims to synthesize novel supramolecules derived from N,N-bis(2-hydroxybenzyl)alkylamine via the simple etherification. The inclusion phenomena of these compounds with guest species will be clarified to propose novel supramolecular structured compounds.
