Selective enhancement of organic dye properties through encapsulation in rotaxane orientational isomers

Chem Commun (Camb). 2023 Apr 20;59(33):4970-4973. doi: 10.1039/d3cc01135f.

Abstract

We report the synthesis and characterisation of [2]rotaxanes based on a stilbazolium dye and a calix[6]arene macrocycle. Since both components are non-symmetric, two orientational isomers are obtained. The two isomers display distinct photophysical and photochemical properties in solution and solid state, superior to the unencapsulated dye.
