Smart chromic materials which change colour due to an external stimulus such as light, mechanical force, temperature and humidity have great potential in commercial applications including as sensors, coatings and drug delivery. Mechanochromic polymeric materials, those polymeric materials which respond to an applied force, are one of the most widely studied and one strategy for their preparation is to covalently bond a mechanochromophore such as spiropyran (SP) into a polymer matrix. Spiropyran when constrained in this way, undergoes a ring-opening reaction to form brightly coloured merocyanine (MC) isomer when subjected to an external force. Although SP has been integrated into a wide range..
