Functionalization of pillar[n]arenes towards optically responsive systems via host–guest interactions

Abstract

In this review, we discuss progress in the field of pillar[n]arene-based optical response systems, focusing on color, fluorescence, circular dichroism, and circularly polarized luminescence signal changes via host–guest interactions.

Fluorescence-enhanced supra-amphiphiles based on pillar[5]arene: construction, controllable self-assembly and application in cell imaging

“…16 Composed of five hydroquinone units connected by methylene at the para -position, pillar[5]arenes have pillar-like structures 17–21 The symmetrical structures and easy functionalization endow pillar[5]arene with good properties in host–guest chemistry. 22–27 Owing to the significant efforts of scientists, numerous stimuli-responsive host–guest recognition motifs of pillar[5]arenes have been constructed and further utilized in the production of various materials, including pillar[5]arene-based supramolecular polymers and supramolecular amphiphiles. 28–32 In stark contrast, only a limited number of attempts have been made to investigate fluorescence properties of pillar[5]arene-based host–guest systems.…”
