Poly[Bis-EDOT-Isoindigo]: An Electroactive Polymer Applied to Electrochemical Supercapacitors
摘要:
Poly[6,6'-bis(ethylene-3,4-dioxythien-2-yl)]-N,N'-dialkylisoindigo (PBEDOT-iI) was synthesized and incorporated as an electroactive material into electrochemical supercapacitors (ESCs) in type I and type III configurations. In type I ESCs, PBEDOT-iI provides a specific power of similar to 360 W/kg and specific energy of similar to 0.5 Wh/kg, while retaining about 80% of its electroactivity over 10 000 cycles. In addition, we report on the use of PBEDOT-iI in type III supercapacitors where operating voltages as high as 2.5 V were achieved with specific energies of ca. 15 Wh/kg, albeit with limited stability.

In addition, high efficiency of energy conversion, excellent field-effect mobility, good on/off current ratios and/or excellent stability can be observed, when the polymers according to the invention are used in semiconductor devices or organic photovoltaic (PV) devices (solar cells).
dye and conjugated unit in opto-electronic materials. Functionalization of IID to increase its structural complexity is demanding for obtaining diversity properties. Herein, we developed a direct C—H/N—H activation method of IIDs via double alkyne annulations and synthesized π-extended IIDs with two pairs of 5/7 membered rings. The structure of the π-extended IIDs was characterized and confirmed by
异靛蓝(IID)作为有机染料和共轭单元广泛应用于光电材料中。为了获得多样性特性,需要对 IID 进行功能化以增加其结构复杂性。在此,我们开发了一种通过双炔环直接 C—H/N—H 激活 IID 的方法,并合成了具有两对 5/7 元环的 π 扩展 IID。通过1 H NMR、13 C NMR、HRMS 和 X 射线晶体分析对 π 扩展 IID 的结构进行了表征和确认。通过紫外-可见吸收、循环伏安法和热重分析对其物理性质进行了表征。与非环形类似物相比,环形产品的吸收系数显着增强。

manipulating the reaction conditions, particularly the choice of solvent, catalyst loading, and reaction sequence, a series of valuable indole derivatives, including isatins and symmetrical and nonsymmetrical isoindigos, were selectively synthesized in good to excellent yields. Furthermore, the gram-scale synthesis of compounds with biological anticancer activity under simple conditions highlights their great
