preparation example Construction

[0046] The preparation method of triphenylene derivatives described in the present invention can be prepared through the following synthetic route:

[0047] 1) When L is selected from , the specific synthetic route is as follows:

[0048]

[0049]Using compound A-a as the starting material, Buchwald-hartwing reactions occur with compounds B-a, B-b, and B-c respectively to form intermediates C-a, C-b, and C-c; then intermediates C-a, C-b, and C-c undergo Buchwald-hartwing reactions with compounds D-a, D-b, and D-c, respectively react to form target compound (I);

[0050] 2) When L is selected from , the specific synthetic route is as follows:

[0051]

[0052] Using compound A-b as the starting material, Buchwald-hartwing reactions occur with compounds B-a, B-b, and B-c respectively to form intermediates C-d, C-e, and C-f; then intermediates C-d, C-e, and C-f undergo Buchwald-hartwing reactions with compounds D-a, D-b, and D-c, respectively react to form target comp...

Abstract

The invention provides a benzophenanthrene derivative and an organic light-emitting device thereof, and relates to the technical field of organic photoelectric materials. The provided benzophenanthrene derivative has excellent hole transport performance and high heat resistance stability, needle holes cannot be formed in a formed film easily and the formed film cannot be aged or deform easily, thefilm is applied to the organic light-emitting device as a hole transport material, the light-emitting efficiency of the device can be improved, the service life of the device is prolonged, and furthermore, the driving voltage of the device can be reduced. The provided benzophenanthrene derivative can further serve as a covering layer, and thus, the light-emitting efficiency of the device is improved.

Description

technical field [0001] The invention relates to the technical field of organic photoelectric materials, in particular to a triphenylene derivative and an organic electroluminescence device thereof. Background technique [0002] Organic light emitting diodes (organic light emitting diode, OLED) have excellent characteristics such as self-illumination, wide viewing angle, fast response time, high luminous efficiency, low driving voltage, thin panel thickness, large-size and rollable panels, and simple manufacturing process. Known as the next generation of "star" flat panel display technology. OLED is a double-injection device, and its structure is a sandwich structure, including an anode, a cathode, and an organic layer sandwiched between the two electrodes. Wherein, the organic layer includes one or more of a hole injection layer, a hole transport layer, a luminescent auxiliary layer, a buffer layer, an electron blocking layer, a light emitting layer, a hole blocking layer, ...
