Oxazine-based molecular switches with finely tunable pH and temperature sensitivity <i>via</i> substituent engineering
We report oxazine-coumarin molecular switches with tunable pH and temperature sensitivity achieved through <i>para</i>-substituent engineering. The switches show pH transition points spanning three units with Hammett constant correlation. Strategic pH adjustment reveals a "sweet spot" where temperature sensitivity is synergistically amplified, offering new possibilities for responsive molecular sensors.
