| titleOfInvention | Benzofuro[2,3-b]pyrazine derivatives and their applications in organic electroluminescent devices |
| abstract | The present invention provides benzofuro[2,3-b]pyrazine derivatives and their application in organic electroluminescence devices, the chemical structural formula of the benzofuro[2,3-b]pyrazine derivatives is: ; Wherein A is carbazole and its derivatives at different positions, triphenylamine and its derivatives at different positions, spirofluorene ring-closing triphenylamine at different positions and its derivatives, spirofluorene at different positions or different positions Acridine and its derivatives. The benzofuro[2,3-b]pyrazine derivatives provided by the present invention are used as light emitters to prepare organic electroluminescence devices, which can obtain high-efficiency electroluminescence performance, and the maximum luminous efficiency can reach 11.5 cantera per ampere , the external quantum efficiency reaches 4.44%, which is close to the theoretical limit of 5% for fluorescent materials as light emitters in electroluminescent devices. |
