Chromism of spiropyrans

, 2018
Smart molecular systems in which spiropyran based molecular switches play a key role are the central focus of this thesis. These systems respond to stimuli (e.g., light, pH, electricity, etc.) through a change in molecular, and thereby material, properties such as color, acidity, or conductivity, amongst others.

Multi-purpose capillary-integrated optical sensors based on spiropyran [PDF]

, 2013
Optical chemical sensors for liquid phase monitoring (overwhelmingly focused on water-based samples) often employ a dye or indicator that is immobilised onto a solid support material.
