First attempts are described to prepare a precursor for an all-carbon analog of indigo, the tetracyclic triene 4. Starting from indan-2-one (9) the alpha-methylene ketone 13 was prepared. Upon subjecting this compound to a McMurry coupling reaction, it dimerized to the bis-indene derivative 17, rather than providing the tetramethyl derivative of 4, the hydrocarbon 14. In a second approach, indan-1-one

pentacyclic small molecule acceptor (IDIDT-C8) with cis-arranged alkyl side chains for the first time. Specifically, four aliphatic groups were introduced on one side of the diindeno[1,2-b:2′,1′-d]thiophene unit to construct the molecular backbone with cis-arranged side chains. Such cis-arranged alkyl side chains can play a significant role in adjusting the crystallinity and molecular packing styles
我们首次合成了一种新型的带有顺式排列的烷基侧链的稠合五环小分子受体(IDIDT-C8)。具体地,在二茚并[1,2- b:2',1'- d ]噻吩单元的一侧引入四个脂族基团以构建具有顺式排列的侧链的分子骨架。这样的顺式排列的烷基侧链可以在调节结晶度和分子堆积方式中起重要作用。因此,可以抑制在光敏层中大分子聚集体的形成。因此,以聚合物PBDB-T作为施主和IDIDT-C8制造的聚合物太阳能电池(PSC)作为受主,最大功率转换效率为10.10%,FF为65.9%,J sc为15.81 mA cm -2,高V oc为0.97 V,这是单结PSC的最高值,到目前为止,稠合的五环电子受体。
