聚(4,4-二烷基-环戊二烯并[2,1-B:3,4-b ']-二噻吩-alt-2,1,3-苯并噻二唑)(PCPDTBT)是一种潜在的异质结型有机太阳能电池的低带隙给体共聚物,其能量转换效率> 5.5%,可以以4,4-二烷基-环戊二烯并[2,1-B:3,4-b']二噻吩(CPDT)和4,7-二溴-2,1,3-苯并噻二唑(4,7-二溴-BT)为单体,通过直接芳基化反应合成。直接芳基化过程导致PCPDTBT的M-n高达40 000,并避免使用昂贵的二硼酸/酯或二锡基单体。
Poly(4,4-dialkyl-cyclopenta[2,1-b:3,4-b']-dithiophene-alt-2,1,3-benzothiadiazole) (PCPDTBT), a potentially interesting low bandgap donor copolymer for bulk heterojunction-type organic solar cells with a power conversion efficiency >5.5%, can be now synthesized in a direct arylation scheme starting from 4,4-dialkyl-cydopenta-[2,1-b:3,4-b']dithiophene (CPDT) and 4,7-dibromo-2,1,3-benzothiadiazole (4,7-dibromo-BT) as monomers. The direct arylation procedure leads to PCPDTBT with an M-n of up to 40 000 and circumvents the use of costly diboronic acid/ester or distannyl monomers.
