    • Although an OLED with the dimethoxy derivative of 1a showed a similar performance, their luminescence intensity and current efficiency were slightly lower than those of 1b. A similar attempt using 1a gave unfruitful results. Nothing was attempted for 1c. Further studies are now in progress and will be published elsewhere
