摘要：
A novel method for studying the merocyanine reversible arrow spiropyran (MC reversible arrow SP) interconversion is proposed, consisting of an acid-induced ring opening of the spiropyran followed by neutralization and stopped-flow measurement of ring closure of the resulting merocyanine; the obtained solvatokinetic data indicated a duality of mechanistic pathways depending on the nature of the dye and solvent polarity.
