Crown ether-cycloparaphenylene hybrid multimacrocycles: insights into supramolecular gas sensing and biological potential.

ABSTRACT: The topologically intriguing multimacrocyclic architecture is endowed with distinct physical and chemical properties. The synthesis of hybrid macrocycles combining crown ethers and cycloparaphenylenes (CPPs) presents a promising strategy for developing multifunctional supramolecular systems. Herein, we first report the precise construction of a series of crown ether-CPP hybrid multimacrocycles with enhanced photophysical properties and diverse host-guest interactions. Notably, the trimacrocyclic hybrid adopts a molecular tweezer-like conformation, resulting in a significantly higher fullerene binding affinity compared to the bismacrocycle. The fullerene complex showed improved conductivity and sensitivity with a limit of detection (LOD) of 19 ppb for NO₂ with excellent cyclic st
