We report the properties of glycoconjugated porphyrin dimers behaving as highly sensitive ratiometric temperature sensors in water. This effect results from interactions between carbohydrate and water altering molecular relaxation kinetics leading to temperature sensitive dual emission. These dimers are robust ratiometric fluorescent probes over a large temperature window (20-90 °C)
