Abstract

An improved azobenzene core capped by two calix[4]arene units isomerizes readily between trans and cis configurations via photochemical and/or thermal means. In addition, the presence of acid (particularly HCl) increases the rate of thermal cis→trans conversion. These enhancements to the functional response, control, and understanding of calixarene-capped azobenzene isomerization are important for future application in the dynamic encapsulation of small chemical species. © 2011 Elsevier Ltd.
