General description

1,1′-Diheptyl-4,4′-bipyridinium dibromide (DHBP) is a heptyl viologen that can be used as an electrochromic (EC) material. It forms a highly efficient quenching system for conjugated polyelectrolyte for the development of organic electronics. It also acts as a redox active electrolyte for electrochemical devices (ECDs).[1][2]

Application

DHBP is an EC material which can be used in the fabrication of electronic devices such as organic light emitting diodes (OLED), supercapacitors, and liquid crystal displays (LCDs).[3][4][5]
