General description

Benzyl viologen dichloride (BVD) is an electrochromic indicator, which contains two chlorine atoms and an organic constituent attached with two nitrogen cations. In a redox reaction, BVD can be reduced in three states with different colors.

Application

BVD can be reduced to its neutral state by using sodium borohydride, which forms an n-type dopant for organic semiconductor based applications. It may be introduced to form a path for the transport of electrons from the thylakoid membranes to the mediator, which can be used in the fabrication of photo-driven bioanode. It also acts as a dopant with 2D layered materials to form an n-type chemical dopant that can be used to enhance the electrical properties of the triboelectric devices.
