The Suzuki–Miyaura reaction of 1,4-dibromo-2-fluorobenzene with two equivalents of arylboronic acids gave fluorinated para-terphenyls. The reaction with 1 equiv of arylboronic acid resulted in site-selective formation of biphenyls. The one-pot reaction of 1,4-dibromo-2-fluorobenzene with two different arylboronic acids afforded fluorinated para-terphenyls containing two different terminal aryl groups
The invention relates to organic electroluminescent devices comprising organic compounds with a double or triple bond, to which at least one aromatic ring is bonded, as emitter compounds. The invention also relates to possible uses of said devices.
The invention concerns polymers, electroluminescence devices, compositions and their use.
