Description
Summary:The design and synthesis of new synthetic macrocycles has driven the rapid development of supramolecular chemistry and materials. Pillar[n]arenes, as a new type of macrocyclic compounds, are used as a promising type of building blocks for switchable supramolecular systems due to their versatile functionalization and the ability of binding toward various guest molecules. A number of guests can form inclusion complexes with pillar[n]arenes and their derivatives in solution, which are sensitive to different external triggers. Interestingly, the pursuit of complex stimuli‐responsive functional materials and devices has largely motivated the shift of pillar[n]arene‐based switches from solution media to surfaces for controllable macroscopic motions on solid platforms. Facilitated by the facile modification of pillar[n]arenes on various solid supports and the dynamic binding of host–guest complexes, numerous functional hybrid materials with adjustable physical or chemical properties and integrated functionalities have been reported in the last decade. Here, the advance of supramolecular switches in solution and on surfaces based on pillar[n]arenes and derivatives with an emphasis on the efforts and the latest contributions from the field is discussed. The supramolecular switches based on pillar[n]arene derivatives that have been investigated in solution and further shifted to the solid surfaces of materials for collective amplified motions controlled by actuations are reviewed. The afforded materials present combined features of stimuli‐responsiveness of pillar[n]arene‐based switches and intrinsic properties of solid supports and show applications in various aspects.
