Scheme 2.
Oxidative-reduction co-reactant ECL pathways.
R − e− | R˙+ | (oxidation at the electrode surface) | |
C − e− | C˙+ | (reduction at the electrode surface) | |
C + C | R + C˙ | (homogenous chemical reactions) | |
C˙+ | *Cr | (homogenous chemical reactions) | |
*Cr + R | R˙− + P | (homogenous chemical reactions) | |
R˙− + R˙+ | R + R* | Or R˙+ + *Cr R* + P (excited state formation species) | |
R* | hv | (emission of light) |
