Embodiment Construction

[0020] Take R as an example for the synthesis of 4-vinylpyridine to synthesize three-(4-pyridylvinylphenyl)amine, and the non-limiting examples are described as follows:

[0021] 1. Preparation of intermediates

[0022]

[0023] Add 1.0g (4mmol) triphenylamine to 50mL of absolute ethanol, after stirring and dissolving at room temperature, mix 4.06g (18.6mmol) HgO and 5.08g (20mmol) I 2 Add in small amounts sequentially, stir vigorously for about 20 hours, evaporate ethanol to dryness, add 30mL of toluene to reflux, and pass the solution directly through a short Al 2 o 3 The sand core funnel, repeated four times. Most of the toluene was distilled off, and a large amount of red solid was precipitated after cooling slightly. After washing with hot methanol under reflux for three times, 2.3 g of white needle-like crystals were obtained, with a yield of 92%.

[0024] 2. Synthesis of target compounds

[0025]

[0026] At room temperature, 2.07g (15mmol) of potassium carbon...

Abstract

Provided is a triphenylamine derivant two-photon light storage material which considers the triphenylamine as initial material, including firstly producing the intermediate tris(4-iodophenyl)amine, then synthesizing the target product. The material is a good two-photon light storage material which has a low two-photon blanch threshold, writes laser power of 8mw, attains blanch with a small exciting power, has a large two-photon absorption cross section.

Description

1. Technical field [0001] The invention relates to a two-photon optical storage material and a preparation method thereof, in particular to a triphenylamine derivative two-photon optical storage material and a preparation method thereof. 2. Background technology [0002] In recent years, with the discovery of strong two-photon absorbing materials, two-photon technology has made a major breakthrough in its application. People are racing to find strong two-photon absorbing materials with large absorption cross section and high upconversion lasing efficiency. The Marder and Prasad groups in the United States are the most representative. Starting from "symmetrical charge transfer" and "asymmetrical charge transfer", these two research groups designed and synthesized many organic molecular materials with strong two-photon absorption, and conducted pioneering applied research. At present, the application of two-photon technology in the fields of three-dimensional high-density da...
