Thermo-responsive white-light emission based on tetraphenylethylene- and rhodamine B-containing boronate nanoparticles.
Boronate nanoparticles with built-in tetraphenylethylene (TPE) have been prepared. Their emissive color tuning by altering the amount of rhodamine B grafted onto the surface gave white-light emissive nanoparticles. They showed reversible and thermo-responsive emission in the temperature range of 5-65 °C in water, which enabled them to serve as a bright nanothermometer.
