Abstract
A spirally configured cis-stilbene/fluorene hybrid material is shown in formula (1), wherein n is 1, 2 or 3, R1 to R6 are independently selected from the group consisting of hydrogen atom, halogen atom, cyano group, alkyl group, cycloalkyl group, alkoxy group, amino group, haloalkyl group, thioalkyl group, silyl group, alkenyl group and aromatic ring group, R8 is a hydrogen atom, tert-butyl group or aryl group, when n is 1, R7 is a hydrogen atom, diarylamino group or 2-diarylamino-spirobifluorene group, when n is 2 or 3, R7 is a hydrogen atom, diarylamino group or 2-diarylamino-spirobifluorene group.
Claims16
A spirally configured cis-stilbene/fluorene hybrid material, comprising a structure of the following General Formula (1),
- wherein, n is 1, 2 or 3, R1 to R6 are each independently selected from the group consisting of a hydrogen atom, halogen atom, cyano group, alkyl group, cycloalkyl group, alkoxy group, amino group, haloalkyl group, thioalkyl group, silyl group, alkenyl group and aromatic ring group, R8 is a hydrogen atom, tert-butyl group or aromatic ring group,
- when n is 1, is 9,9′-spirobifluorene group, diarylamino group or 2-diarylamino-spirobifluorene group,
- when n is 2 or 3, R7 is a hydrogen atom, diarylamino group or 2-diarylamino-spirobifluorene group.
An organic electroluminescent device, comprising:
- a first electrode layer;
- a second electrode layer;
- and
- an organic luminescent unit, deposited between the first electrode layer and the second electrode layer, wherein the organic luminescent unit has at least a spirally configured cis-stilbene/fluorene hybrid material as shown in General Formula (1),
- wherein, n is 1, 2 or 3, R1 to R6 are each independently selected from the group consisting of a hydrogen atom, halogen atom, cyano group, alkyl group, cycloalkyl group, alkoxy group, amino group, haloalkyl group, thioalkyl group, silyl group, alkenyl group and aromatic ring group, R8 is a hydrogen atom, tert-butyl group or aromatic ring group,
- when n is 1, is 9,9′-spirobifluorene group, diarylamino group or 2-diarylamino-spirobifluorene group,
- when n is 2 or 3, R7 is a hydrogen atom, diarylamino group or 2-diarylamino-spirobifluorene group.
