Embodiment 1

[0067] In a 1000 mL flask with cooling tube and stirrer, put 500 mL of toluene, 54.11 g of 1,1,3,5,5-pentamethyl-3-phenyltrisiloxane and 74.51 g of 4-vinyl -1-cyclohexene-1,2-epoxy, followed by nitrogen purging for 60 min. After that, 0.0063 g of platinum(0)-1,3-diethylene-1,1,3,3-tetramethyldisiloxane was put into the flask, and the temperature of the flask was increased to 40° C., followed by Stir for 4h. The residual solvent was removed by distillation, thereby preparing a compound represented by formula 1, which is designated as I. 97% purity as determined by HPLC. m / e:588.24; 1 H NMR (400MHz, Chloroform-d) δ7.51(m, 1H), δ7.28(m, 2H), δ7.18(m, 2H), δ1.45(m, 4H), δ1.60(dd ,2H),δ2.87(dd,2H),δ1.60-1.70(dd,4H),δ1.43(m,2H),δ1.3(m,4H),δ0.21(m,12H) , δ0.66(s, 3H), δ0.8(m, 4H).

Embodiment 2

[0071] In a 1000 mL flask with cooling tube and stirrer, put 800 mL of toluene, 33.26 g of 1,1,5,5-tetramethyl-3,3-diphenyltrisiloxane and 91.3 g of allyl glycidol ether, followed by a nitrogen purge for 60 min. After that, 0.0063 g of platinum(0)-1,3-diethylene-1,1,3,3-tetramethyldisiloxane was put into the flask, and the temperature of the flask was increased to 70° C., followed by stirring 4h. Residual solvent was removed by distillation. Thus, a compound represented by formula 2 was prepared and designated as II. HPLC assay has a purity of 97%, m / e: 560.24; 1 H NMR (400MHz, Chloroform-d)δ7.53(m,2H),δ7.29(m,4H),δ7.19(m,4H),δ3.63(d,4H),δ3.38(m ,4H),δ2.86(dd,2H),δ2.38(dd,4H),δ1.5(m,4H),δ1.02(m,4H),δ0.21(s,12H).

Embodiment 3

[0075] In a 1000mL flask with a cooling tube and a stirrer, put 800mL of toluene, 30g of 1,1,5,5-tetramethyl-3-diphenyltrisiloxane and 50g of allyl alcohol, followed by nitrogen purging for 60min . After that, 0.003 g of platinum(0)-1,3-diethylene-1,1,3,3-tetramethyldisiloxane was put into the flask, and the temperature of the flask was increased to 70° C., followed by stirring 4g. Residual solvent was removed by distillation to obtain a crude product of an intermediate terminal with a hydroxyl group on one side. The crude product was separated by column chromatography of ethyl acetate and petroleum ether to obtain an intermediate product with a purity of 98% liquid chromatography. The above-mentioned intermediate was added to a three-necked flask containing 300 mL of anhydrous dichloromethane, and 21 g of triethylamine was added. Next, 45 g of acryloyl chloride were introduced slowly while stirring at 0°C. The residual solvent is removed by distillation, thereby preparing ...

Abstract

The invention provides an ink composition, a package structure and a semiconductor device. The ink composition comprises a photocurable silicon-containing monomer component, an active diluent component and a photoinitiator component, wherein the photocurable silicon-containing monomer component is a photocurable silicon-containing monomer or a combination of a plurality of photocurable silicon-containing monomers; each photocurable silicon-containing monomer has a structural formula as shown in the specification; and in the structural formula, at least one of A1 and A2 is an acrylate group, and at least one of A1 and A2 is an epoxy group. Monomers containing two functional groups, i.e., acrylate and epoxy, are mixed for use, so a free radical-cation hybrid curing system can be formed; andthe material integrating the advantages of the acrylate and epoxy photocurable silicon-containing monomers is obtained, and an organic barrier layer with a high photocuring rate, a low curing shrinkage rate and moderate base material adhesive force and hardness is achieved. Therefore, requirements on a packaging film in the prior art are better met.
