Embodiment 1
[0035] The preparation process of IDDT-TBA:
[0036] 6,6,12,12-Tetrakis(4-hexylphenyl)-6,12-dihydrodithieno[2,3-d:2',3'-d']-s-benzobisindeno [1,2-B:5,6-b']dithiophene-2,8-dicarbaldehyde (107.4 mg, 0.1 mmol) and TBA (44 mg, 0.22 mmol) were dissolved in 10 mL of chloroform, then 0.1 mL of piperidine was added . The solution was stirred at 80°C for 8 hours. The mixture was then diluted with chloroform and washed three times with brine. The organic phases were combined and washed with MgSO 4 dry. After removing the solvent, the resulting residue was purified by column chromatography using hexane as eluent to give IDDT-TBA (96.8 mg, 90.1%) as a dark blue solid. Implementation route:
[0037]
[0038] Such as image 3 as shown, 1 H NMR (400MHz, CDCl 3 ): δ8.65(s,2H), 8.16(s,2H), 7.62(s,2H), 7.22(d,8H), 7.13(d,8H), 4.58(m,8H), 2.56(m, 8H), 1.62-1.59 (m, 8H), 1.38-1.27 (m, 36H), 0.90-0.84 (m, 12H). Such as Figure 6 as shown, 13 C NMR (101MHz, CDCl 3 ):δ178.57,161.03,...
Embodiment 2
[0041] The preparation process of IDT-TBA: 4,4,9,9-tetra(4-hexylphenyl)-4,9-dihydro-s-benzobisindeno[1,2-B:5,6- B']dithiophene-2,7-dicarbaldehyde (96.25mg, 0.1mmol) and TBA (44mg, 0.22mmol) were placed in a two-necked reaction flask, and after adding 10mL of ethanol, slowly heated to 80°C until all the reactants were dissolved. After adding 0.1mL of triethylamine to ethanol, the solution turns red-blue. After the reaction, the product precipitates out of ethanol. After filtration, it is purified by column chromatography using hexane as the eluent to obtain IDT-TBA as a dark blue solid. (93.4 mg, 97%).
[0042] Implementation route:
[0043]
[0044] Such as figure 1 as shown, 1 H NMR (400MHz, CDCl 3 ): δ8.67(s,2H), 7.78(s,2H), 7.74(s,2H), 7.30(d,8H), 7.26(d,8H), 7.14-7.08(m,8H), 4.63- 4.54 (m, 8H), 2.59-2.55 (m, 8H), 1.59-1.21 (m, 36H), 0.89-0.85 (m, 12H). Such as Figure 5 as shown, 13 C NMR (101MHz, CDCl 3 ):δ178.51,160.86,160.05,159.77,157.67,156.12,149.76,142.3...
Embodiment 3
[0047] The preparation process of FTBr-TBA: the precursor 5,5'-(9,9-bis(6-bromohexyl)-9H-fluorene-2,7-diyl)bis(thiophene-2-carbaldehyde) (71.5mg ,0.1mmol) and TBA (44mg, 0.22mmol) were placed in a two-necked reaction flask, and after adding 10mL of ethanol, slowly heated to 80°C. Since the precursor had an alkyl chain bromide and had a high structural activity, there was no need to add it later Catalyzed by any base, the solution slowly turned blue-purple after 8 hours of reaction. After the reaction was completed, the column chromatography using hexane as the eluent was purified to obtain FTC8-TBA as a dark blue solid.
[0048] Implementation route:
[0049]
[0050] Such as Figure 4 as shown, 1 H NMR (400MHz, CDCl 3 )δ8.72(s,2H),7.96-7.95(d,2H),7.88(d,2H),7.83-7.79(m,4H),7.67-7.66(m,2H),4.70-4.60(m, 8H), 2.16-2.12(m,4H).
[0051] Figure 7 It is the thermal weight loss curve of IDDT-TBA. It can be seen that the material will reach the glass transition temperature w...
