PhenN_2Naph
Developed in the Miyake lab, this dihydrophenazine PC (PhenN_2Naph) was applied in a number of small molecule and polymer syntheses (see highlight below). It was designed as a strong excited state reductant for oxidative quenching applications.
The photophysical and electrochemical properties are:
-
E0(2PC•+/1PC*) = -1.69 V vs. SCE]
-
E0(2PC•+/1PC) = 0.21 V vs. SCE]
-
λ(max,abs) = 343 nm (εmax = 5950 M-1cm-1); note: absorption tails into visible, white or blue LED can be used
-
τ (triplet, lifetime) = 4.3 µs
-
Ï• (triplet, QY) = 2 %
PhenO_1Naph_Biph
The phenoxazine PC (PhenO_1Naph_Biph), developed in the Miyake lab, was demonstrated efficacious in a number of small molecule and polymer syntheses (see highlight below). It was designed as a strong excited state reductant for oxidative quenching applications. The oxidized radical cation of PhenO_1Naph_Biph is more oxidizing than PhenN_2Naph by ~0.4 V. PhenO_1Naph_Biph has photophysical and electrochemical properties similar to Ir(ppy)3 than it can serve for its direct replacement.
The photophysical and electrochemical properties are:
-
E0(2PC•+/1PC*) = -1.80 V vs. SCE]
-
E0(2PC•+/1PC) = 0.65 V vs. SCE]
-
λ(max,abs) = 388 nm (εmax = 26600 M-1cm-1); note: absorption tails into visible, white or blue LED can be used
-
τ (triplet, lifetime) = 480 µs
-
Ï• (triplet, QY) = 90 %
