An Electrochemical Color-Switchable RGB Dye: Tristable [2]Catenane

摘要

The concept of an electronic paper display (E-PAD),a low-cost and reflective display that feels like a document printed on conventional paper,emerged in the late 1990s.Several prototypes of pixel components in the E-PADs have been demonstrated.For example,the Bell Labs/E Ink utilizes microencapsulated suspensions of charged white particles in a black fluid.Another demonstration of the pixel components is based on the phenomenon of electrowetting to manipulate microscale liquid droplets.
