Photophysical and electrochemical data for pyrazine derivatives.
| Pyrazine derivatives | λabs (nm) | λem (nm) | Molar extinction coefficient (M−1 cm−1) | E1/2reda (V) | Eg (eV) |
|---|---|---|---|---|---|
| CNDIPY | 330/400 | 460 | 50,000 | −1.7 | 2.67 |
| TETPY | 292/390 | 450 | 40,000 | −1.76 | 2.76 |
| DIPY | 296/370 | 440 | 20,000 | −1.64 | 3.10 |
E1/2reda are half-wave reduction potential measured in ACN versus Ag/AgCl. Eg (HOMO-LUMO gap) calculated from Cyclic Voltammogram.
