Synthesis, properties and applications of biphenyl functionalized 9,9-bis(4-diphenylaminophenyl)fluorenes as bifunctional materials for organic electroluminescent devices
Four new bifunctional materials, namely BPTF, CBPTF, CMBPTF and BPVTF, having 9,9-bis(4-diphenylaminophenyl)fluorene as a molecular platform and biphenyl derivatives as end-capping substituents were synthesized and characterized. Their optimized structure
