Herein, we report the molecular design and synthesis of two novel organic co-adsorbers DBA-1((Z)-2-cyano-3-(5-(4-(cyclohexa-1,5-dien-3-ynyl(phenyl)amino)phenyl)-1-hexyl-1H-indol-3-yl)acrylic acid) and (DBA-2) 5-((5-(4-(diphenylamino)phenyl)-1-hexyl-1H-indol-3-yl)methylene)pyrimidine-2,4,6(1H,3H,5H)-trione with D-D-A (donor-donor-acceptor) architecture. We have combined the strong electron donating
在这里,我们报告了两种新型有机共吸附剂DBA-1((Z)-2-cyano-3-(5-(4-(cyclohexa-1,5-dien-3-ynyl(phenyl )氨基)苯基)-1-己基-1H-吲哚-3-基)丙烯酸)和(DBA-2)5-((5-(4-(4-(二苯基氨基)苯基)-1-己基-1H-吲哚-3-基)亚甲基)嘧啶-2,4,6(1 H,3 H,5 H)-具有DDA(donor-donor-acceptor)结构的三酮。我们将强供电子三苯胺基团与连接到不同受体/锚定基团上的吲哚部分结合在一起,作为染料敏化太阳能电池的共吸附剂,并且首次展示了锚定/受体单元在它们的共吸附中的作用。属性。在这项研究中,氰基乙酸和巴比土酸被用作在共敏化剂的锚定基团DBA-1和DBA-2分别。从密度泛函理论(DFT)获得的它们的电化学和光物理性质以及分子几何结构被用来证明共敏化剂结构对DSSC光伏性质的影响。我们已经
