EfficientElectrogenerated Chemiluminescence of PyrrolopyrroleAza-BODIPYs in the Near-Infrared Region with Tripropylamine: InvolvingFormation of S 2 and T 2 States

Efficient electrogenerated chemiluminescences (ECLs) of three pyrrolopyrrole aza-BODIPYs in the near-infrared region by using tripropylamine as a coreactant are reported. Kinetic analysis based on Marcus theory indicates the direct formation of S2 and T2 states through the electron transfer reaction, which affects the ECL efficiencies.
