Highly durable colour/emission switching of fluorescein in a thin film device using “electro-acid/base” as in situ stimuli†
Abstract
A radical ion from electroreduced p-benzoquinone (BQ) was introduced as a new source of convenient in situ base for colour/emission switching of fluorescein in thin film devices. The devices show excellent switchability and reversibility with no degradation during our extended switching test of 1500 cycles.
