Ortho-substituent effect on fluorescence and electroluminescence of arylamino-substituted coumarin and stilbene.
[structure: see text] Newly synthesized arylamino-substituted coumarins and stilbenes show enhanced fluorescence emission (bluer and brighter) both in solution and in solid film. Pure blue efficient electroluminescence with 2.7% and 4.1% of external quantum efficiency can be achieved with MeC1 and XTPS, respectively.
