Abstract

The stimuli‐responsive behavior in smart materials is attributed to specific design features within a polymer and the choice of its architecture: random and block copolymers differ in their responsive behavior. Considering the substantial investigations into various systems, another classification is possible and entails the response of the polymer to single or multiple stimuli. This chapter outlines solution properties of multi‐stimuli‐responsive azopolymers, in which main chain comprises of aliphatic or tegylated calix[4]arenes as well as dibenzo‐18‐crown‐6‐ethers joined via —N=N— azo‐bridges. The idea behind using calixarenes and crown ethers as repeating units of polymers was to produce photo‐switchable systems capable of host‐guest interactions. The tegylated poly(azocalix[4]arene)s also reveal the lower critical solution temperature (LCST) and upper critical solution temperature (UCST) behavior in water and in low molar mass alcohols, respectively. Photoisomerization of the tegylated poly(azocalix[4]arene)s affects their thermal responsiveness.
