Embodiment 1
[0108] Example 1 Preparation of IO-4Cl Compound
[0109] Refer figure 2 The synthetic route, 199.1 mg of Compound 1 (purchased from Suli Organic Optoelectronics Technology (Beijing) Co., Ltd.) and 214.8mg Compound 2 (purchased from Suli Organic Optoelectronics Technology (Beijing) Co., Ltd.) added to 50ml round bottom flask. The air in the bottle is introduced into the bottle to carry out argon protection. A 20 mL of chloroform and 0.2 ml of pyridine were added. Then, the round bottom flask was moved into a 65 ° C oil bath to stir for 15 hours. After the reaction was completed, 208.6 mg of Compound IO-4Cl was purified by column.

Embodiment 2
[0113] Example 2 A photovolus battery is prepared based on a PBDB-TF / ITCC system
[0114] PBDB-TF (from SOLAMERMETERIALINC Purchase) with ITCC (purchased from SOLAMERMETERIALIALINC) with a weight ratio of 1: 1 common mixed dissolved in chlorobenzene to prepare 10 mg / ml of blended activatable layer solution, then 0.5% by volume 1, 8 - iodine octane is prepared in the blended spiral solution. Device preparation is followed by: First, the commonly used anode modification layer PEDOT: PSS is spin coated on the surface of ITO, annealing at 150 ° C for 20 minutes. The substrate was then moved to the glove box, and the above blended activated layer solution was then copies into a membrane (2000 rmp / min, 90s) on the PEDOT: PSS layer. The film was then annealed at 100 ° C for 10 minutes. After the substrate is cooled, ZnO nanoparticles (dispersed in methanol solution) are spin on the active layer film. Finally, at approximately 10 -4 A 100 nm aluminum layer was evaporated under press...
Embodiment 3
[0117] Example 3 Preparation of photovoltaic cells based on PBDB-TF / IT-4F system
[0118]PBDB-TF (from SolamerMeterialInc Purchase) with IT-4F (purchased from SolamerMeterialInc) with a weight ratio of 1: 1 co-mixed in chlorobenzene, then prepared a total of 10 mg / ml of a blended lamination solution, and then 0.5% by volume ratio 1 8-biode octane is added to the blended spiral solution. Device preparation is followed by: First, the commonly used anode modification layer PEDOT: PSS is spin coated on the surface of ITO, annealing at 150 ° C for 20 minutes. The substrate was then moved to the glove box, and the above blended activated layer solution was then copies into a membrane (2000 rmp / min, 90s) on the PEDOT: PSS layer. The film was then annealed at 100 ° C for 10 minutes. After the substrate is cooled, ZnO nanoparticles (dispersed in methanol solution) are spin on the active layer film. Finally, at approximately 10 -4 A 100 nm aluminum layer was evaporated under pressure ...
