Embodiment 1

[0028] Weigh 2g (0.005952mol) of hexafluorobisphenol A and dissolve it in about 20mL of THF, pour it into a three-neck flask placed in an ice bath, add 0.65g (0.006436mol) of triethylamine (Et 3 The amount of N should be slightly excess than the HCl generated in the reaction), and after stirring with nitrogen for 30 minutes, dissolve 0.5383g (0.006223mol) of acryloyl chloride in 10ml THF and quickly add it dropwise to the above solution, and leave the ice bath after reacting for 1 hour. The reaction was continued overnight at room temperature. The reaction solution was distilled under reduced pressure at 95°C in a rotary evaporator to remove tetrahydrofuran and triethylamine in the reaction system; 20g (0.2162mol) of epichlorohydrin was added, transferred to a three-necked flask with a constant temperature water bath at 50°C, and N 2 After 30min, add 0.25g of solid NaOH every 0.5h, add 12 times, a total of 3g; raise the temperature to 60°C, and react at a constant temperature ...

Embodiment 2

[0033] All the reaction raw materials and operating methods used are the same as in Example 1, except that the addition of erbium-containing complex EDPM is 0.3394g to obtain 0.3wt% fluorine-containing erbium-containing polymer with erbium content.

Embodiment 3

[0035] All the reaction raw materials and operating methods used are the same as in Example 1, except that the addition amount of the erbium-containing complex EDPM is 2.4934 g to obtain a fluorine-containing erbium-containing polymer with an erbium content of 1 wt%.

[0036] figure 1 Shown is the synthesis route of the fluorine-containing polymerizable monomer (FA) prepared in Example 1.

[0037] figure 2 Shown is the infrared spectrogram of the fluorine-containing active monomer (FA) prepared in Example 1. It can be seen from the figure that the reaction product of fluorine-containing bisphenol A and acryloyl chloride is at 1636cm -1 The characteristic peak of C=C double bond appeared at , and the 928cm -1 is the characteristic peak of the epoxy group, and 3367cm -1 The -OH absorption peak at the position basically disappears, which shows that the phenolic hydroxyl groups at both ends of the fluorinated bisphenol A have basically completed the reaction with acryloyl chl...

Abstract

The invention relates to a method for synthesizing an ultraviolet-writable fluorine-containing erbium-containing polymer waveguide amplifier material and belongs to the field of synthesis of polymer near-infrared light-emitting materials. According to the method, a fluorine-containing active monomer containing an olefin double bond and an epoxy group, an erbium-containing complex and epoxypropyl methacrylate are subjected to ternary polymerization to prepare a fluorine-containing erbium-containing polymer near-infrared light-emitting material so that the compounding of an erbium ion and the polymer at the molecular level is achieved and the fluorescence quenching caused by uneven concentration of a rare earth complex due to phase separation generated by uneven doping is avoided. Polymer optical waveguide amplifier micro-patterns with stripe structures are prepared by carrying out lithography development on a polymer film obtained by a spin coating through a direct ultraviolet-writing technology, compared with the traditional process, copying processes such as evaporating a metal film layer and ion etching are not needed and thus the process steps are reduced and meanwhile, the cost is decreased and the method is an advantageous method for producing a polymer waveguide amplifier.
