Synthesis of diketopyrrolopyrrole containing copolymers: A study of their optical and photovoltaic properties

The diketopyrrolopyrrole-based copolymers PDPP-BBT and TDPP-BBT were synthesized and used as a donor for bulk heterojunction photovoltaic devices. The photophysical properties of these polymers showed absorption in the range 500-600 nm with a maximum peak around 563 nm, while TDPP-BBT showed broadband absorption in the range 620 - 800 nm with a peak around 656 nm. The power conversion efficiencies (PCE) of the polymer solar cells based on these copolymers and [6,6]-phenyl C61 butyric acid methyl ester (PCBM) were 0.68% (as cast PDPP-BBT:PCBM), 1.51% (annealed PDPP-BBT:PCBM), 1.57% (as cast TDPPBBT:PCBM), and 2.78% (annealed TDPP-BBT:PCBM), under illumination of AM 1.5 (100 mW/cm2). The higher PCE for TDPP-BBT-based polymer solar cells has been attributed to the low band gap of this copolymer as compared to PDPP-BBT, which increases the numbers of photogenerated excitons and corresponding photocurrent of the device. These results indicate that PDPP-BBT and TDPP-BBT act as excellent electron donors for bulk heterojunction devices. ? 2010 American Chemical Society.

Preparation method of diketopyrrolopyrrole compound with bi[n]alkynyl-containing terminal group

The invention relates to a preparation method of a diketopyrrolopyrrole compound with a bi[n]alkynyl-containing terminal group. 3, 6-bis(thiophene-2-yl)pyrrolo[3, 4-C]pyrrole-1, 4-dione (DPP) and a bi[n]alkynyl group-containing micromolecule undergo a reaction to produce the diketopyrrolopyrrole compound and n is an integer greater than or equal to 1. The preparation method comprises that a terminal alkyne-DPP derivative and 1-alkyne undergo a Glaser coupling reaction to produce a desired product of which n is 1 or 2, or comprises that a soluble dibromo-DPP derivative and bi[n]alkyne undergo a Cadiot-Chodkiewicz coupling reaction to produce a high-yield desired product of which n is greater than or equal to 2. The diketopyrrolopyrrole compound can be widely used in fields of organic light-emitting diodes, field-effect tubes and solar cells.
