Single-color pseudorotaxane-based temperature sensing

Colored pseudorotaxane solutions can be used to assess temperature changes over large temperature windows. The color intensity of our novel pseudorotaxane systems decreases gradually from -50 to +50 degrees C with no shift in absorption maximum, making these and similar pseudorotaxanes attractive ca...

Summary:Colored pseudorotaxane solutions can be used to assess temperature changes over large temperature windows. The color intensity of our novel pseudorotaxane systems decreases gradually from -50 to +50 degrees C with no shift in absorption maximum, making these and similar pseudorotaxanes attractive candidates for single-wavelength colorimetric temperature sensors.
