Phase transition of spiropyrans: impact of isomerization dynamics at high temperatures

Isomerization behaviors of spiropyran derivatives in neat condensed phase were studied to understand their unusual phase transitions including cold-crystallization after extreme supercooling down to −50 °C. Compounds with different functional groups were compared, and the equilibrium between isomers...

Summary:Isomerization behaviors of spiropyran derivatives in neat condensed phase were studied to understand their unusual phase transitions including cold-crystallization after extreme supercooling down to −50 °C. Compounds with different functional groups were compared, and the equilibrium between isomers at high temperatures was found to determine phase transitions. Temperature-dependent isomerization dynamics between spiropyran and merocyanine forms strongly impact the phase transition of molecular switches.
