Embodiment 1

[0015] When X is an oxygen atom, the synthetic route is as follows:

[0016]

[0017] The synthesis method is:

[0018] Synthesis of Triphenylamine Dialdehyde (Compound 1)

[0019] Phosphorus oxychloride POCl 3 Added to DMF, the reaction system was cooled with an ice-water bath and moisture was isolated. After stirring at room temperature for 1 hour, triphenylamine was added. Keep the reaction at 120°C for 12 hours, pour the mixture into ice water (10-15 times the volume of the reaction solution), add 20% NaOH solution to neutralize, a yellow solid is precipitated, and the crude product is purified by silica gel chromatography (eluent : ethyl acetate: petroleum ether = 1: 2), to obtain a bright yellow solid, which is triphenylamine dialdehyde. The molar ratio of triphenylamine, phosphorus oxychloride and N,N-dimethylformamide is 1:3.1-5.9:6.1-9.9. The melting point is 142-143°C. IR: 1692cm -1 (C=O).

[0035] The synthesis method is:

[0036] Preparation of Bromothiophenemethyltriphenylphosphine

[0037] Weigh 2-methylthiophene (5.01g, 50mmol), add in 250ml round bottom flask, then add carbon tetrachloride 150ml, NBS powder (10.7g, 60mmol), BPO powder 0.1g, heat to CCl 4 After reflux for 2h, the reaction solution gradually changed from a light yellow solution to a darker yellow. The reaction solution was filtered and washed with CCl 4 Wash the filter residue and collect the resulting CCl 4 solution, spin off CCl 4 A yellow oily liquid was obtained, to which water was added to remove water-soluble impurities, and CHCl 3 Extraction, adding anhydrous Na 2 SO 4 Let dry overnight. Filter out Na 2 SO 4 , transfer the resulting yellow solution into a 250ml flask, add PPh 3 (10.7g, 50mmol) and CHCl 3 100ml, heating and stirring, to CHCl 3 Reflux, stop heating after 2h of reaction. During t...

Abstract

A Y-type two-order non-linear optical chromogen containing triphenylamine group and its preparing process are disclosed. It can be used as two-order non-linear optical material used in remote communication, data storage, phase conjugation, etc.

Description

technical field [0001] The invention relates to a Y-type second-order nonlinear optical chromophore containing a triphenylamine group, a preparation method and application thereof. Background technique [0002] The construction of "information highway" has attracted more and more attention from governments, economic organizations and the general public, and is known as a key development industry in the 21st century. At present, relying on the development of electronics and microelectronics technology, human beings have established a fairly complete and systematic information network. However, with the progress of society, the existing information systems still cannot meet human's requirements for fast and accurate information processing, transmission, and transformation. At the same time, due to the physical limit of the electron itself—including the transmission speed limit of the electron as an information carrier (the maximum electron transmission speed is 600km / s) and t...
