A squaraine-based small molecule (USQ-BI) bearing 3H-benzo[e]indoline was synthesized as an electron donor, and the corresponding organic solar cells show power conversion efficiency of 5.35 % with an excellent short circuit current of over 15 mA cm?2. The hole mobility of USQ-BI was about 5 times (9.57×10?5 vs. 2.00×10?5 cm2 V?1 s?1) higher than that of indoline-based squaraine.

The present invention belongs to the field of indole synthesis technology, in order to solve the current synthesis of indole and its derivatives with ethylene glycol as raw material, the conditions are relatively harsh, the structure of the main catalyst is complex, expensive and other issues, providing a synthesis method of indole derivatives. Pt/Al2O3 catalyst supportingPt/Al2O3was prepared by impregnation with acidicAl2O3as the support, using aniline compounds, ethylene glycol, and the preparedPt/Al2O3 Catalyst for catalytic reaction, control reaction temperature of 190 °C, reaction 24h, after the end of the reaction, first add water to stir evenly, and then with dichloromethane for extraction, organic phase by rotational distillation to remove the solvent, and then with petroleum ether, ethyl acetate as the eluent column chromatography separation, you can obtain the target product. A broad spectrum of the Catalytic System ofPt/Al2O3Supported Catalysts with Good Catalytic Effect inthe Glycol Aniline Reaction was studied, and the substrate range of substituted aniline was mainly expanded.
