Embodiment

[0055] Following the above technical scheme, this embodiment provides an optical material containing a phenanthroimidazole structure, which is denoted as the target product 8, and the structural formula of the target product 8 is as follows:

[0056]

[0057] The preparation method of the target product 8 of the present embodiment comprises the following steps:

[0058] Step 1, dissolve 10mmoL of 4-bromobenzaldehyde, 10mmoL of 4-tert-butylaniline and 10mmoL of 9,10-phenanthrenequinone in acetic acid-ammonium acetate buffer solution, stir and mix at 120°C for 2h, and mix well Finally, the crude product of 4-bromophenanthroimidazole was obtained, and the crude product of 4-bromophenanthroimidazole was washed with methanol, separated by filtration, vacuum dried and purified by column chromatography to obtain the purified product of 4-bromophenanthroimidazole.

[0059] In step one of the present embodiment, the preparation process of acetic acid-ammonium acetate buffer solution...

Abstract

The invention provides an optical material containing a phenanthroimidazole structure, and a preparation method and application thereof. According to the optical material containing the phenanthroimidazole structure, the efficient fluorescence quantum efficiency characteristic of anthracene is used as a bridge, and by means of the electron-withdrawing carbazole group electron-donating property of phenanthroimidazole, carrier injection and transmission are more balanced, so that the device performance can be improved; and meanwhile, a large-steric-hindrance distortion structure is adopted, so that the fluorescence quantum efficiency of a solid film aggregation state is improved, and efficient blue light emission can be performed in an organic solvent. When the optical material containing the phenanthroimidazole structure is used as a light-emitting layer material for manufacturing an organic light-emitting semiconductor device, the light-emitting efficiency and the light-emitting brightness of the organic light-emitting semiconductor device can be improved, and the structural formula of the material is as shown in formula I in the specification.

Description

technical field [0001] The invention belongs to the technical field of photoelectric materials, and relates to an optical material containing a phenanthroimidazole structure, in particular to an optical material containing a phenanthroimidazole structure, a preparation method and an application. Background technique [0002] Road driving safety has always been the most important issue for vehicle owners and traffic management departments, but the hidden dangers caused by low-visibility driving environment (rain, snow, dense fog, haze and other low-visibility weather conditions) are obvious. When the vehicle is driving at night or in low-visibility weather conditions, when there are no light-spotting objects or reference objects on both sides of the road, the light is easy to astigrate, the light becomes dim, and the visibility becomes low. [0003] Due to the problem of the viewing angle or brightness of road signs, road guidance signs are difficult to identify or fail at ni...
