Description

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).

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).
