Description

Electrochromism is the electrochemical response of the materials which show the reversible color-changes by electrochemical reaction. One of the typical examples is violene species in which the color development is observed in the radical ionic state. However, in generally, the radical ionic state is not expected to show high stability. The use of cyanine substructure might stabilize the colored species, but the substructure does not exhibit good redox properties. We propose the new molecular design for the preparation of stabilized electrochromic materials taking advantage of the cyanine substructures. The design is consistent with the cyanine substructure connected as end groups of redox active pi-electron system. Herein, we report about the construction of electrochromic materials, in which the colored state is stabilized by the cyanine substructures.
