The invention belongs to the field of
organic semiconductor materials, and discloses a novel
anthracene luminescent material, a preparation method and applications thereof; the preparation method includes the steps of: in an
inert gas
atmosphere, performing a bromination reaction to
anthracene, 9-bromoanthracene or 9,10-dibromoanthracene as
raw material with addition of a bromination agent under
catalysis by
metal or Lewis acid; then performing
palladium-catalyzed
coupling reaction to introduce
substituent groups on the 2nd, 3rd, 6th, 7th, 9th and 10th or 2nd, 3rd, 6th, 7th and 9th loci of theanthracene. The
luminescent material has a symmetrical functionalized molecular structure of
anthracene, so that luminescent intensity,
color purity and stability are improved. For the first time, through
catalysis, the
substituent groups are introduced onto the 2nd, 3rd, 6th, 7th, 9th and 10th or 2nd, 3rd, 6th, 7th and 9th loci of the anthracene, so that molecular planarity is damaged and [pi]-[pi] stacking is inhibited, thus improving the luminescent efficiency and
quantum yield performance of the material are enhanced, controlling the luminescent range of the material, inhibiting
crystallization, improving film-forming property and improving charge
transmission performance.
