Towards the rational design of -(1,3-dimethylbutyl)-'-phenyl-1,4-benzenediamine (6PPD) electrochemical sensor.

-(1,3-Dimethylbutyl)-'-phenyl-1,4-benzenediamine (6PPD) is a common additive in tires. 6PPD protects rubber from oxidative damage by ozone. Leaching of 6PPD in the environment leads to the formation of harmful byproducts such as 6PPD quinone.
