Preparation method of 2-bromo-5-(2-ethylhexyl) thiophene

The invention provides a preparation method of 2-bromo-5-(2-ethylhexyl) thiophene. The preparation method comprises the following steps: 1) mixing thiophene, 2-ethylhexyl acyl chloride and aluminum chloride anhydrous in anhydrous dichloromethane, stirring the mixture at room temperature to react, and then carrying out quenching and post-treatment to obtain 2-(2-ethylhexyl) thiophene; 2) mixing theprepared 2-(2-ethylhexyl) thiophene, hydrazine hydrate, triethylene glycol and sodium hydroxide, heating and stirring the mixture to reflux, after reaction, changing a reflux device into a distillingdevice, adding water, carrying out distillation by water steam, and separating the liquid to obtain 2-(2-ethylhexyl) thiophene; and 3) mixing the prepared 2-(2-ethylhexyl) thiophene, hydrobromic acidand hydrogen peroxide, stirring the mixture at room temperature to react, and separating the liquid to obtain the 2-bromo-5-(2-ethylhexyl) thiophene. The preparation method provided by the inventionis mild in condition, high in yield, relatively easy in post-treatment and suitable for scaled preparation, avoids use of low temperature and dangerous reagents, and is safe and simple to operate.

Solution-processed and high-performance organic solar cells using small molecules with a benzodithiophene unit

Three small molecules named DR3TBDTT, DR3TBDTT-HD, and DR3TBD2T with a benzo[1,2-b:4,5-b′]dithiophene (BDT) unit as the central building block have been designed and synthesized for solution-processed bulk-heterojunction solar cells. Power conversion efficiencies (PCEs) of 8.12% (certified 7.61%) and 8.02% under AM 1.5G irradiation (100 mW cm-2) have been achieved for DR3TBDTT- and DR3TBDT2T-based organic photovoltaic devices (OPVs) with PC 71BM as the acceptor, respectively. The better PCEs were achieved by improving the short-circuit current density without sacrificing the high open-circuit voltage and fill factor through the strategy of incorporating the advantages of both conventional small molecules and polymers for OPVs.
