Protecting a squaraine near-IR dye through its incorporation in a slippage-derived [2]rotaxane.
The photophysical properties and chemical stability of a squaraine derivative were enhanced after using Na+ ions to template a high-yield slippage synthesis of a [2]rotaxane from the dye and a molecular cage.
