In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Synthesis of Poly(4,4-dialkyl-cyclopenta[2,1-b:3,4-b’]dithiophene-alt-2,1,3-benzothiadiazole) (PCPDTBT) in a Direct Arylation Scheme, published in 2012-04-17, which mentions a compound: 58656-04-5, mainly applied to arylation polydialkyl cyclopentadithiophene benzothiadiazole, Application of 58656-04-5.
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-cyclopenta[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 Mn of up to 40,000 and circumvents the use of costly diboronic acid/ester or distannyl monomers.
This literature about this compound(58656-04-5)Application of 58656-04-5has given us a lot of inspiration, and I hope that the research on this compound(Tricyclohexylphosphonium tetrafluoroborate) can be further advanced. Maybe we can get more compounds in a similar way.
