Poly(boron-dipyrromethene)—A Redox-Active Polymer Class for Polymer Redox-Flow Batteries

The utilization of boron-dipyrromethene (BODIPY) as active group for the charge storage process in a battery application is reported. Two BODIPY-containing copolymers were synthesized and electrochemically characterized. The polymers feature redox processes at 0.7 V and −1.5 V vs AgNO3/Ag, which enable the application in a redox-flow battery setup.
