Embodiment Construction

[0030] Taking R as ethyl as an example, non-limiting examples are described as follows:

[0031] 1. Preparation of intermediate (I)

[0032] Weigh 12g (0.016mol) of thiourea and dissolve it in 100mL of methanol, add 16g (0.016mol) of acetylacetone and 1mL of hydrochloric acid, and let it stand at room temperature for 40-50 hours, the solution turns yellow, and a large amount of bright yellow crystals precipitate out. After filtering and drying, 13.2 g of bright yellow crystals were obtained, with a yield of 75%. That is the intermediate (I) 2-mercapto-4,6-dimethylpyrimidine.

[0033] 2. Preparation of intermediate (II)

[0034] NaOH (4.0 g, 0.1 mol), 100 mL of water and 2-mercapto-4,6-dimethylpyrimidine (14.0 g, 100 mmol) were successively added into a 250 mL round bottom flask, and 9.4 g of 1 was added dropwise under stirring at room temperature, 2-Dibromoethane (0.05mol), continue to stir for 60-80 hours after dripping to obtain a large amount of gray solid, after filteri...

Abstract

A branched pyrimidine derivative of a two-photon three-dimensional optical storage material, characterized in that it has a compound shown in the following chemical formula: in the test, R is selected from ethyl or propyl or butyl or pentyl or hexyl or hydroxyethyl or Hydroxyethylcarboxylate or phenyl. The compound has a large two-photon absorption cross-section and good stability, and is an ideal organic two-photon three-dimensional optical storage material whether it is formulated into a solution or processed into a film.

Description

1. Technical field [0001] The invention relates to an organic two-photon three-dimensional optical storage material and a preparation method thereof, in particular to a kind of multi-branched pyrimidine derivatives of an organic two-photon absorption material that can be used in two-photon three-dimensional optical storage and a synthesis method thereof. 2. Background technology [0002] Organic materials with large two-photon absorption cross-sections have good application prospects in frequency upconversion lasers, optical clipping, photodynamic therapy, frequency upconversion fluorescence microscopy, three-dimensional optical information storage, and three-dimensional micromachining. aroused great interest of researchers. After more than 20 years of development, many two-photon absorbing materials with practical value have been discovered, and two-photon absorbing materials have entered the stage of practical research with practical significance. Among the many applicati...
