Abstract Three simple and small donor-acceptor type conjugated moieties, namely (2Z, 2′Z)-3,3'-((hexylazanediyl)bis (4,1-phenylene))bis (2-(pyridin-2-yl)acrylonitrile) ( DPA-PA-1) , (2Z, 2′Z)-3,3'-((dodecylazanediyl)bis (4,1-phenylene))bis (2-(pyridin-2-yl)acrylonitrile) ( DPA-PA-2) , (2Z,2′Z)-3,3'-((allylazanediyl)bis (4,1-phenylene))bis (2-(pyridin-2-yl)acrylonitrile) DPA-PA-3 have been synthesized
摘要 三个简单且小的供体-受体型共轭部分,即 (2Z, 2'Z)-3,3'-((hexylazanediyl)bis (4,1-phenylene))bis (2-(pyridin-2-yl)丙烯腈) ( DPA-PA-1) , (2Z, 2'Z)-3,3'-((dodecylazanediyl)bis (4,1-phenylene))bis (2-(pyridin-2-yl)丙烯腈) ( DPA-PA-2)、(2Z,2'Z)-3,3'-((烯丙基氮杂二基)双(4,1-亚苯基))双(2-(吡啶-2-基)丙烯腈)DPA-PA- 3 已根据 Knoevenagel 缩合合成。此处烷基(己基、十二烷基、烯丙基)二苯胺 (DPA) 部分充当电子供体,吡啶-乙腈 (PA) 部分充当电子受体。这些部分最近对光电应用表现出极大的兴趣。DPA-PA-1-3的结构由FT-IR、 1 H NMR和13 C N
