A high molecular weight alternating naphthalene diimide–bithiophene copolymer (poly{[N,N′-bis(2-octyldodecyl)-naphthalene-1,4,5,8-bis(dicarboximide)-2,6-diyl]-alt-5,5′-(2,2′-bithiophene)} (PNDIOD-T2)) has been prepared by direct (hetero)arylation polymerization (DHAP). Its structure and properties were investigated in comparison with the Stille-prepared commercial analog, N2200. It was found that the new DHAP-derived PNDIOD-T2 and known N2200 have similar optical absorption spectra and HOMO/LUMO energy levels but slightly different 1H NMR spectra. Inverted all-polymer solar cells using PNDIOD-T2 as the acceptor and PCE12 or PCE10 as the donor polymer showed slightly superior performances compared to similar N2200 devices. All-polymer solar cells with 7.3% efficiency could be achieved with PNDIOD-T2 blends without the use of a processing additive. These results demonstrate that low-cost and eco-friendly DHAP-based n-type semiconducting polymers are promising for developing high performance all-polymer solar cells.

聚（萘二酰亚胺ALT联噻吩）通过直接制备（杂）芳基化聚合法高效全聚合物太阳能电池
高分子量交替萘二酰亚胺二噻吩共聚物（聚{[ Ñ，Ñ ' -双（2-辛基十二烷基） -萘-1,4,5,8-双（二甲酰亚胺）-2,6-二基] - ALT -通过直接（杂）芳基化聚合（DHAP）制备了5,5'-（2,2'-联噻吩）}（PNDIOD-T2））。与Stille制备的商业类似物N2200比较，研究了其结构和性质。发现新的DHAP衍生的PNDIOD-T2和已知的N2200具有相似的光吸收光谱和HOMO / LUMO能级，但略有不同11 H NMR谱。与类似的N2200器件相比，使用PNDIOD-T2作为受体并使用PCE12或PCE10作为施主聚合物的倒置全聚合物太阳能电池显示出稍强的性能。PNDIOD-T2共混物无需使用加工助剂即可实现7.3％的全聚合物太阳能电池效率。这些结果表明，低成本且环保的基于DHAP的n型半导体聚合物有望开发出高性能的全聚合物太阳能电池。
