Two donor-acceptor (D-A) type conjugated porous polymers (CPPs) named P(TPA-TBTh) and P(TPA-F-TBTh) were prepared on the ITO glass electrodes through Stille coupling reaction under solvothermal condition using triphenylamine (TPA) as the donor and non-fluorinated or di-fluorinated 4,7-bis(thiophen-2-yl)benzo[c] [1,2,5]thiadiazole (TBTh) as the acceptor. The results show that both amorphous CPPs exhibit ambipolar properties in the electrochromic switching and they present completely different morphologies. In the p-type doping process, P(TPA-TBTh) and P(TPA-F-TBTh) fade respectively from neutral purple and neutral reddish purple to oxidized gray. After the n-type doping, P(TPA-TBTh) and P(TPA-F-TBTh) show grass green and emerald green reduced forms respectively. The introduction of fluorine atoms onto the polymer skeleton reduces the highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO) energy levels, and makes P(TPA-F-TBTh) have a slightly lower band gap than P(TPA-TBTh). Besides, the non-fluorinated P(TPA-TBTh) and the di-fluorinated P(TPA-F-TBTh) exhibit different electrochromic kinetic properties. The two D-A type CPPs not only provide new structural designs for multicolor electrochromic materials with ambipolar properties, but also achieve the rare green reduction states, thereby deserving attention and further exploration.

以三苯胺(TPA)为原料，在溶剂热条件下通过Stille偶联反应在ITO玻璃电极上制备了两种供体-受体(DA)型共轭多孔聚合物(CPPs)P(TPA-TBTh)和P(TPA-F-TBTh)供体和非氟化或二氟化 4,7-双（噻吩-2-基）苯并[c] [1,2,5]噻二唑（TBTh）作为受体。结果表明，两种无定形 CPP 在电致变色切换中均表现出双极性，并且呈现出完全不同的形貌。在p型掺杂过程中，P(TPA-TBTh)和P(TPA-F-TBTh)分别从中性紫色和中性红紫色逐渐变为氧化灰色。n型掺杂后，P(TPA-TBTh)和P(TPA-F-TBTh)分别呈草绿色和翠绿色还原型。在聚合物骨架上引入氟原子，降低了最高占据分子轨道（HOMO）和最低未占分子轨道（LUMO）能级，使得P(TPA-F-TBTh)的带隙比P(TPA-待定）。此外，非氟化P(TPA-TBTh)和二氟化P(TPA-F-TBTh)表现出不同的电致变色动力学特性。这两种DA型CPP不仅为具有双极性的多色电致变色材料提供了新的结构设计，而且还实现了罕见的绿色还原态，值得关注和进一步探索。非氟化 P(TPA-TBTh) 和二氟化 P(TPA-F-TBTh) 表现出不同的电致变色动力学特性。这两种DA型CPP不仅为具有双极性的多色电致变色材料提供了新的结构设计，而且还实现了罕见的绿色还原态，值得关注和进一步探索。非氟化 P(TPA-TBTh) 和二氟化 P(TPA-F-TBTh) 表现出不同的电致变色动力学特性。这两种DA型CPP不仅为具有双极性的多色电致变色材料提供了新的结构设计，而且还实现了罕见的绿色还原态，值得关注和进一步探索。
